Write Command in Shell

Is there a write command in shell? It seems like there should be, but I guess most people just use the ">" and "<" symbol. It just seems like it would make things simpler to just use the "|" pipe symbol.

I can verify it was on Minix 1 (1980's). Here is the man page (very short!):
Command: tee - divert standard input to a file
Syntax: tee [-ai] file ...
Flags: -a append to the files, rather than overwriting
-i ignore interrupts
Examples: cat file1 file2 | tee x # Save and display two files
pr file | tee x | lpr # Save the output of pr on x
Tee copies standard input to standard output. It also makes copies on
all the files listed as arguments.
Edit: It looks like it is an old UNIX command. You can find its manual entry for Version 7 UNIX under volume 1, section 2 here or here.

Serial Write - 8Mb file to write. Write command can only do 256 Bytes at a time. How to split up?

First, thanks for this resource. I've used this forum quite a bit as a "lurker" and it's gotten me this far. Hoping to learn a bit, so I can contribute
Anyway, my issue is this:
I am ultimately trying to write an 8Mb binary file to an 8Mb Serial Flash device via the Total Phase Aardvark. The writes to the flash device I am using are limited to 256 bytes per write command. The vi program attached is capable of writing 256 bytes at a time, but not anything more. I realize I need to incorporate some sort of "For Loop" (and I understand that I'd want to do it =(File Size)/256 interations, but I can't seem to figure out how.
Does anyone have any quick advice to drive me in the right direction?
Thank you!

Well, you seem to have answered your own question, so it's not clear what your specific issue is. Is it how to extract 256 bytes at a time?
As for the code... umm... I'm not entirely sure what you're trying to accomplish with the whole top half of your code, but it seems to me that almost the whole thing can be replaced by a single call to the Read Binary File function. What is the format of these binary files?

Hi Martin,
I don't have a specific answer sorry, however I do recall seeing a number of OSS notes around BPM archiving whilst searching for a different issue last year - have you checked on there for anything relevant to your currnet version and SP level? There were quite a few notes if memory serves me well!

Merge/concatenate animation codec movie files in the command line/shell

We know how to join 2 mp4/h264 movies together in the command line/shell via MP4Box.
We have not been able to find a similar tool for joining to Quicktime Animation codec movie together via command line/shell.
Anyone know how to do that of have suggestions?
thanks,
paul

Hi,
I'm also having trouble with this same issue. I've been trying to change the Quicktime Default Setting to 10-bit uncompressed (btw codec works fine out directly out of QT and other apps), or to use the command line to do quick renders of tiff frame sequences to QT 10-bit. I think its a problem with my syntax on the command line. As per the manual I set up a fileout in a script with 10-bit as the codec, opened the script in Textedit and followed the instructions on p393, and dropped it into the include/startup directory. Below is a copy of the Textedit view of the script output settings. Also, If I want to use these settings the command line what should I change? The quotation marks, commas etc?
"QuickTime", "Shake 3 QT 1", "Apple FCP Uncompressed 10-bit 4:2:2",
0, "100W@c6000WDcsuHpoe10pFnKA6W230PPMMRH#0LgfI5ALV1EaKGn3DG3214QaPb03SeOBPg00K1bY AESIIW0KAbabF7YWOQan8401v6QvQehFnRYIBt9be1B4AEjYA6ci8YmM#IKXCg5aRMZC2MXBM0Ani04w HAJLmBrQ97MtegeEEO9d5oBoxCgv7GNhEOvai8INwFwb2roIf91bvbr040HAK4IYCW0",
0, 44100, 16);
I get the same message returned in Terminal:
error: - NRiCompressor - corrupted input data (length)
The QuickTime codec specified in the global default could not be selected. The system default codec will be selected.
So it renders to Animation. Something else I found was that the example on p393 in the manual is for 10-bit uncompressed - so I tried copying it right off the page, into Textedit, and into the include/startup dir - still no joy.
Can anyone shed any light on the matter?

There are guesses, but I would check:
1. Does the target directory exist?
2. Does the CF application server account does not have

Update command in Shell script

Hi friends
sqlplus -s / <<END
set feedback on;
update tran2 set sno=1;
exit;
END
when i am using update command in shell script like above
it is updating the database well...but i just want to know how many rows it is updating and i dont want to commit
for that
sqlplus -s / <<END
set feedback on;
update tran2 set sno=1;
set feedback off;
rollback;
exit;
END
It's working fine
is there any other method to do the same

Well what's exactly your requirement? The current requirement doesn't make a lot of sense.
How many row is going to be updated depends on where clause, if you have no where clause that essentially updating whole table, the number of row updated is count of your rows.

WRITE command gives unexpected value when currency is JPY (japanse yen)

Hi All
I am getting unexpected value for below WRITE command but only when the currency is JPY (Japan Yen)
lv_amount = 1215.40
lv_currency = u2018JPYu2019.
write lv_amount to ev_amount_ext left-justified no-gap NO-GROUPING currency lv_currency.
Value wrongly gets as ev_amount_ext = 121540 (Decimal takes as full value)
Appreciate your help if you have any idea on this please
Many Thanks
Iver

Hi,
use like this
lv_amount = '1215.40'
lv_currency = u2018JPYu2019.
write lv_amount to ev_amount_ext left-justified no-gap NO-GROUPING currency lv_currency.
other wise.
data lv_amounts type string.
move lv_amount to lv_amounts.
lv_currency = u2018JPYu2019.
write lv_amount to ev_amount_ext left-justified no-gap NO-GROUPING currency lv_currency.

Error message after write command

Hi,
i have a program that will display an error message after a write command...
it goes like this: when you click on the button change material it will go to the transaction MM02 and when you saved your changes the value of the table will refresh but when it was refresh and there is no data that would retrieve an error message will pop-up no data selected..but when you click on the check button or enter the previous data still appears which is wrong it should go back to the selection screen...
can anybody can help me with this?
thank you...
regards,
mae

how will i do it?
thank you

Write command

how i can use write in
event AT SELECTION-SCREEN.

Hi,
We can not use the WRITE command in this Event
The event AT SELECTION-SCREEN is the basic form of a whole series of events that occur while the selection screen is being processed.
The standard selection screen in an executable program or in the logical database linked to it is automatically called between the INITIALIZATION and START-OF-SELECTION events. When you call the selection screen, and when users interact with it, the ABAP runtime environment generates selection screen events, which occur between INITIALIZATION and START-OF-SELECTION.
You can define event blocks for these events in your program to change the selection screen or process user input.
You can use the COMMENT to write the text in the selection screen ..
To place comments on the selection screen, you use:
SELECTION-SCREEN COMMENT [/]pos(len) comm [FOR FIELD f]
                                          [MODIF ID key].
This statement writes the comm comment on the selection screen. For comm, you can specify a text symbol or a field name with a maximum length of eight characters. This character field must not be declared with the DATA statement, but is generated automatically with length len. The field must be filled before the selection screen is called. You must always specify the pos(len) addition. Only if there are several elements in one line can you omit pos.
The text comm will be displayed, starting in column pos, for a length of len. If you do not use a slash (/), the comment is written into the current line; otherwise a new line is created.
You use FOR FIELD f to assign a field label to the comment. f can be the name of a parameter or a selection criterion. As a result, if the user requests help on the comment on the selection screen, the help text for the assigned field f is displayed.
The MODIF ID keyaddition has the same function as for the PARAMETERS statement. You can use it to modify the comment before the selection screen is called.
Here is the exampel Program
REPORT demo_sel_screen_select_comment.
SELECTION-SCREEN COMMENT /2(50) text-001 MODIF ID sc1.
SELECTION-SCREEN SKIP 2.
SELECTION-SCREEN COMMENT /10(30) comm1.
SELECTION-SCREEN ULINE.
PARAMETERS: r1 RADIOBUTTON GROUP rad1,
            r2 RADIOBUTTON GROUP rad1,
            r3 RADIOBUTTON GROUP rad1.
SELECTION-SCREEN ULINE /1(50).
SELECTION-SCREEN COMMENT /10(30) comm2.
SELECTION-SCREEN ULINE.
PARAMETERS: s1 RADIOBUTTON GROUP rad2,
            s2 RADIOBUTTON GROUP rad2,
            s3 RADIOBUTTON GROUP rad2.
SELECTION-SCREEN ULINE /1(50).
INITIALIZATION.
COMM1 ='Radio Button Group 1'.
COMM2 ='Radio Button Group 2'.
LOOP AT SCREEN.
    IF screen-group1 = 'SC1'.
      screen-intensified = '1'.
      MODIFY SCREEN.
    ENDIF.
ENDLOOP.

How to write commands to Crossbow MDA300 with LabVIEW?

I am able to read data from Nodes using LabVIEW, but I would like to write commands to the nodes using LabVIEW. How can I do that? I am using Iris mote, MDA300, MTS420, MTA 310 sensor boards and MIB520 USB board gateway board and I had got LabVIEW drivers when I purchased the kit. Kindly help.

I am also using the same components which you have used. but i don't have drivers for it. can you please tell me from where i can get them.

Triggering write commands

Hi,
I currently have a load cell that I have interfaced with a RS232 port. The load cell is sending string data which I am collecting using the I/O Instrument Assist manager in LabView. I am collecting that data, converting to dynamic type and writing to a LabView meaurement file. I have this setup in a while loop to keep collecting data. I am also writing string data via another RS232 port to a stepper motor driver. I am currently just doing testing of the driver/motor using the LabView example code Basic_read_and_write.vi. What I basically wish to do is that when the load cell reading reaches a target value, I send a diferrent string to the stepper motor driver. The initial write string to the drive cell is "M+", which makes the motor move forward at constant velocity. The motor will apply a force on the load cell. When this force reaches a target value, I want the write string to the driver to change to "M-", which moves the stepper motor backwards at constant velocity.
I was thinking of using the case structure function and having the "true" case as the move forwatd string and the "false" case as the move backward string. I was then going to use the function in the string palette that outputs a boolean "true" or "false" depending on the value of the input string, where the "true" or "false" output is wired to the case structure.
Does anyone have some better suggestions than what I have thought of? This seams a bit convuluted. Can someone see a modification of the 2 port read/write example. Any help would be really appreciated.
Cheers,
Dave

Hello Dave,
This sounds like the exact programming logic you should be using. Case structures are the perfect tool for decision making for a continuous process. You basically want to execute different code (write commands) based upon input values from earlier code (read commands). This is exactly what case structures are used for.
Thank you and good luck,

How to call a HP-UX command or shell script from Forms 4.5

Does anybody know how to call a unix command or shell script to get a files list of HP-UX server from Oracle Forms 4.5 on client side? I tried to use DBMS_PIPE package to get it done but I failed. Please let me have the solution if anybody knows how. Very urgent!

I tried the host command before and it just let me shell to the DOS environment but not HP-UX environment as Forms was running on Windows platform. So, I could not run a unix command or a shell script. Is DBMS_PIPE the only way to get it done?

Output format of sqlplus commands under shell script

hi experts
Can you help with some problems please?
1.) I try to run shell script from dbms_scheduler, which runs sqlplus and the output of sqlplus commands is written to file using command spool. To this point everything is running ok.
My problem is, that output of this file is: (e.g.)
SQL> PROMPT ****************USERB******************
****************USERB******************
SQL> --SELECT sid
SQL> -- FROM v
SQL> -- WHERE audsid = SYS_CONTEXT('userenv','sessionid');
But I don't want the whole first line in the output file. I only want the output of this command, like on the second line.
2.) How Can I write two outputs from sqlplus using command spool running at the same time into one file?
Like in first issue described above. The main sqlplus create a job and this execute the background sqlplus using shell script. But both, the main and the background sqlplus are written to output file at the same time. But only one is written into. But I want the both outputs in the file.
How Can I do that, if I can?
Thanks a lot.
