Shell Programming and Scripting

Hi Team,

I'm using HP UX. I want to pass a variable dynamically as input while executing the script and that value need to be replaced with a string in the script. I tired SED, in the command line its working but while I keep the same command in the script its not working. Can someone help me on this please. Below is the SED what I used.

Code:

sed 's/xyz/abc/g' log.txt > log1.txt

where xyz is the value in the script and abc is the new value what we are passing dynamically.

Thanks in advance

What you are asking for might be:

Code:

sed "s/xyz/$1/g" log.txt > log1.txt

Code:

#! /usr/bin/ksh
############

arg=$1

sed 's/xyz/'${arg}'/g' log.txt > log1.txt
# eos

The second one is working, thanks

and the first one, which is essentially the same solution but simply avoids an unnecessary variable and has simpler quoting, too.
