Starting Execution At A Certain Point In A Shell Script

Question

Im working on a script that will do the stage 2 installation for me and its kind of a pain to have to run the whole script again just to see if something that I fixed at the very end was actually fixed. Is there a GOTO command or something like that that will let me skip certain chunks of the script? (ex. place GOTO line 128 at line 5 so I dont have to wait X amount of minutes for it to get there)

Answer 1

You can put "labels" in comments and use sed to pass only the part of the script you want to be executed to bash. This won't work well if there are required functions defined above the starting line.
For example:
cookies.sh:
#!/bin/bash
echo cookies
echo ice cream
#tacos
echo tacos
In ~/.bashrc:
bgoto() {
sed -n "/^#$1\$/,\$ p" "$2" | bash
And finally run the script starting at #tacos with:
[foutrelis@foutboxd ~]$ bgoto tacos cookies.sh
tacos
It's not pretty, but it should do what you want.
