usage of history command inside shell script

bsaheb · 12-04-2008, 04:36 AM

Hi All,

I need to write a script which requires to display the output for the shell commands.

I am able to retrieve the result for "ls" but the "history" command execution is failed.

Please let me know if there a way to specify the history command inside the shell script and get the output of it.

Sample Script:

#!/bin/bash
ls
history

Rgrds,
saheb

Note that within a script, the history mechanism is disabled.

hi,

give the permission to the script..

chmod 755 a.sh or chmod 777 a.sh

then execute, you will get the output
