Ksh: Send a mail in case grep finds something
I want to search a file if it contains special strings and if yes, the records found should be mailed.

I can either do it with a temporary file:

Code:
/usr/bin/grep somestring somefile > /tmp/tempfile && /usr/bin/mail -s "Found something" email@mycomp.com < /tmp/tempfile

... or by running the grep command twice:

Code:
/usr/bin/grep -q somestring somefile && /usr/bin/grep somestring somefile | /usr/bin/mail -s "Found something" email@mycomp.com

I wonder if there is another short and smart way doing this without using a file and without using grep twice and without do-loops?

This should run with AIX 6.1, preferably under ksh version 88.

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/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).
