hi, I am trying to write a unix script that recursively goes into each directory and 'touches' the file to update the time stamp.....any help on how to go about it is appreciated..

I'm not near a unix box, so this is: # untested find /mydir -type f -print|while read myfile do touch myfile done

Sorry, but I corrected a syntax error: I'm not near a unix box, so this is: # untested find /mydir -type f -print|while read myfile do touch $myfile done

find /mydir -type f |xargs touch

I am new to unix, I saved the file as test.sh and changed permissions using chmod 777 test.sh. When i try to run using ./test or test I keep getting the message "command not found"...wht am i doing wrong here?

I'm guessing that the directory where script test.sh resides isn't in your PATH. If your current directory is the directory where test.sh resides and it still doesn't work, try this: ./test.sh If you want unix to search your current directory, append a period to end of PATH: PATH=$PATH:. export PATH I must warn you about the security considerations of doing this - especially if you are the root user.
