$1 is the first argument passed to the script. The script's name is $0. > 2. how do I add to this script the count of the number of lines in a file? > i.e. let's say cat's man page. `wc -l` counts the number of lines in a file (or passed on stdin). > 3.lastly,let's say I want to print the first line of each 3-char.h file in > /usr/include/lib..how can I accomplish this? `head -1` displays the first line of a file. To select your files, use shell globs - * matches 0 or more characters, ? matches any single character. Check the man pages for wc and head also; they can do some pretty neat (well, maybe not all that neat - but very useful) stuff when passed other arguments. -- SGI products are used to create the 'Bugs' that entertain us in theatres and at home. - SGI job posting Geek Code 3.1: GCS d? s+: a- C++ UL++$ P++>+++ L+++>++++ E- W--(++) N+ o+ !K w---$ O M- V?
