Shell Programming and Scripting

Yes, I just figured that out. And surprised!

This works only in ksh and its derivates like ksh93 and in zsh.

Hi,

if i use for loop , the input variable dosnt have the line by line value but the entire output of ls.Can someone tell me how to read it line by line using for loop

The previous example wasn't the best solution, this should be better:

Code:

#!/bin/sh

IS_VAR=0

for file in *
do
if [ "$input" = "hi" ]
then
  IS_VAR=1
  echo $IS_VAR
  break
fi
done
echo $IS_VAR

Hi,

Can someone help me in using awk or sed for finding out if the output contains a particular string.Because i cannot use * here in the for loop.

for example ,
if my output is
string1
string2
string3
string

i want to check if the output has the word "string".if i use grep "string" it shows me all the words displayed in the output.but i just need the output string.i tried using grep "^string$".But this also doesnt help me.

Thanks ,
Padmini
