A simple shell script to execute a command package

satimis

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

1. #!/bin/bash
   
2. 
   
3. cmd1="code1" #the exact/full command
   
4. cmd2="code2" #the exact/full command
   
5. cmd3="code3" #the exact/full command
   
6. etc.
   
7. 
   
8.      cmd1 || exit 1
   
9.      cmd2 || exit 2
   
10.      cmd3 || exit 3
    
11.      ...
    
12.      cmdn || exit n
    
13.      echo "Build environment entered!"
    
14. exit 0

复制代码

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/abc_dir" output.  If no output OR empty output the shell should exit, not continue executing further commands

TIA
