Top Forums Shell Programming and Scripting How to echo output of a UNIX command (like ls -l ) using shell script.? Post 302882487 by gacanepa on Tuesday 7th of January 2014 07:37:28 AM

I am a little confused as to what you're really trying to do. But assuming you want to display the output of a command via a shell script, here's what you should do:
Create a script, say test.sh, with the following contents:
Code:
#!/bin/bash
ls -l

The code snippet above assumes you are using the bash shell. For other shells you need to find the path to them (for ksh, it should be /bin/ksh).
Give the script permissions to execute:
Code:
chmod 755 test.sh

Then run the script:
Code:
./test.sh

You should see displayed the output of the ls -l command in your screen.
I would highly recommend you take a look at The Linux Command Line, which IMHO is the best Linux book for starters (and for seasoned users as well!). This and many other essential topics are explained in detail. Also, you can download it for free from the link above.
Hope it helps.

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list. Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1). FILES
