Hi all, I have a script that scan files, find old templet and replace it with new one. 1 #!/bin/ksh 2 # Loop through every file like this 3 for file in file_name 4 do 5 cat $file | sed "s/old_templet/new_templet/g" > $file.new 6 #do a global searce and replace and put the results 7 mv $file.new $file 8 #rename $file.new to original name of file 9 done 1. How can i take the 3 parameters (file name, new templet and old templet) from the command row ? 2. How can add option to add big new templet (that include few rows) instead the old templet. 10x Amir

call the script like this <script_name> <file_name> <old_templet> <new_templet> add 3 lines at the start of your script #!/bin/ksh file_name=$1 old_templet=$2 new_templet=$3 your sed line needs to be parameterised (if i understand what you are doing) cat $file | sed "s/$old_templet/$new_templet/g" > $file.new old_templet and new_templet will be words/strings etc... is this what you were after?
