UNIX commands

My little cheatsheet for all those line commands I can't always remember:

general:

find . -name \*.html -print Find the names of all files, starting at the present directory (.) that end in '.html'

find . -name \*.html -print | xargs grep "texts" Find the names of all files, starting at the present directory (.) that end in '.html'. Next pipe that list of names (xargs), GREPing each one for the given text string.

ls -laR Directory listing of all files, done recursively

ls -laF | grep / Directory listing of directories only

tar cvf (file name) .

tar xvf (file name)

file (name) to find out what kind of file it is

cp -r cfdocs ../basetest/cfdocs Copy whole subdirectory

touch (file name) To update file access parms

which (program name) To find which copy of a program will execute

more with / (search) After the first screen full of MORE output, type '/' followed by a search string to get where you want to be.

admin stuff: (root)

passwd -d (userID) Reset password to 'prompt for new' at logon

find . ! -user siteadm -exec chown siteadm {} \; Find all files not owned by 'siteadm' and change the ownership of them to 'siteadm'

find . ! -perm -g+w -exec chmod g+w {} \; Find all files without the grup write privilege and set them to group write
