Script to search a word

[nash11]

I am new to writing script , could give some advise how to write it?

I have a text file "printout.txt" , I want to check the content this file , if the word "failure" appear in this file for over two times , then do xxxxxxxx ,
what can I do ? thx

That depends on how much you want to do with it.

0. Is the mere existance of the word enough to take action?
1. Is there more info on that line you need?
2. Is there more info in the surrounding lines you need?

In case 0, just use grep

if [ "`grep failure printout.txt`" == "" ]; then
echo no failure found
else
# Do some actions here
fi

If you want more security, use GNU grep and -w (grep whole word only)

If you need flexibility, use perl

#!/usr/bin/perl

use strict;
use warnings;

@ARGV = ("printout.txt");
while (<>) {
m/\b failure \b/x or next;
print STDERR "Found a failure on line $.\n";
system "echo Help | mailx -s failure you\@local.host";
}

thx reply,

what I want is simple , if found the word "failure" appear OVER TWO TIMES in the file , then mail the message to me , what can I do ? thx.

awk -F"failure" 'BEGIN{cnt=0} {cnt+=(NF-1)} END{print cnt}' printout.txt

gives you the number of the word "failure" in the file.

Several ways to count the number of lines with 'failures'

# perl -nle'/\bfailure\b/ and$n++}END{print$n' printout.txt

# grep -w failure printout.txt | wc -l

So, in a script, you could do

--8<---

n=`grep -w failure printout.txt | wc -l`
if [ $n -ge 3 ]; then
# actions here
fi
-->8---

Hi

Here another shell one-liner:

# [ $(grep -c failure printout.txt) -ge 2 ] && do_xxxxxxxx

Did the answers help you? Did we interpret the question the way you meant it?

echo found more them 2 failure
fi
