I've found a solution using 'eval'. Why do I need to execute another command to use piping in shell script?
You don't. It is not needed or desirable to put the command into an Environment Variable (like $cmd in your script).
Your whole script should be just:
Code:
#!/bin/bash
cd /
find . -type f -name *.txt | awk '{ printf "FILE: "$1; system("less "$1);}' | egrep 'FILE:|$1'
Note that the first parameter in "find" should be the name of a directory or "." (current directory) and in your case you should confine the search to files (-type f).
There are probable bugs in the command line. The "egrep" in particular.
Not clear what the script is meant to do but searching down from root is not usually a good idea because you will find directories and files which you cannot read.

Hi,
Can't you have a pipe in a command string ?
If I try the following I get errors.
Why ?
> cmd="ls -lrt | grep xyz"
> $cmd
|: No such file or directory
grep: No such file or directory
xyx: No such file or directory
Thanks in advance

shells
shells(4) File Formats shells(4)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/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/pfcsh, /usr/bin/pfksh,
/usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.
Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).
