Can any one send me a shell script to search and replace a string in a directory neelima

Hi I'hv written for changing spaces to ":"...This might help you...If you mean to say that..you are searching string and Replacing Directory path. # Change spaces to ":" so the tokens can be parsed. DIRPATH=`echo $DIRPATH | sed -e 's; ;:;g'`

We were just talking about the gres script, global regular expression, at this link: http://www.computing.net/unix/wwwbo... Since it's sed it, doesn't change text in place. You have to redirect the output to a temporary file and then change the file name.

Thanks for ur response,But I want to replace a sting in a file with another string for ex :There is a directory "ABCD" which contain 50 files ,among these 50 files there are 20 files which conatin a particular string(lets say "hello world").I want to replace "hello world" with "hello something"... Sorry for tat ambigious question. neelima

I forgot to specify that there can be any number of sub folders in that directory neelima

Did you even bother reading the other thread? Place the following commands in a file called 'gres' and make it executable: # D & R's gres file="myfilename" pattern=$1 replacement=$2 A="`echo | tr '\012' '\001' `" sed -e "s$A$pattern$A$replacement$A" $file # end gres Execute it like this: gres "hello world" "hello something" If you want to seach a directory tree, use find: find . -type f -print|while read myfile do echo "$myfile" done Or use the recursive option of ls: ls -1R|while read myfile do if [[ -f $myfile ]] then echo "$myfile" fi done
