A simple script to execute a command package

Aug 9th, 2005

Hi folks,

I'm prepared to write a simple script to execute 20+ commands and could not figure out how to make use of "loop" subject to certain conditions.

If without conditions

 Help with Code Tags 
 Shell Scripting Syntax (Toggle Plain Text) 
#!/bin/bash
 
cmd1="code1" #the exact/full command
cmd2="code2" #the exact/full command
cmd3="code3" #the exact/full command
etc.
 
     cmd1 || exit 1
     cmd2 || exit 2
     cmd3 || exit 3
     ...
     cmdn || exit n
     echo "Build environment entered!"
exit 0
#!/bin/bash

cmd1="code1" #the exact/full command
cmd2="code2" #the exact/full command
cmd3="code3" #the exact/full command
etc.

     cmd1 || exit 1
     cmd2 || exit 2
     cmd3 || exit 3
     ...
     cmdn || exit n
     echo "Build environment entered!"
exit 0

It will be a long script. Please advise how to apply "loop" to shorter the script executing all command subject to following conditions

1) All commands except cmd3 should have no output. If there is any it needs to confirm either to continue OR to exit the shell

2) cmd3 should have "/mnt/lfs" output. If no output OR empty output the shell should exit, not continue executing further commands

TIA
