Hello all.

I'm a college student currently assigned to build a small shell for a Linux OS. Nothing really fancy like Bash, but I need to access the $PATH env variable so I'm able to use those common commands like cd or ls. The code is being built using C (compiling with gcc), so I could really use some help in has how I can, everytime a non absolute command is given, search through the directories listed in $PATH.

The man on the function execlp states that it already does this, but i'm not getting any results. Am I doing anything wrong?


BTW, I'm not only a noob programmer, but a Linux noob also :P 1st post...

Thx in advance.

Ah, forget about it. 2mins after I posted, I re-re-re(...)-re-read the man page on execlp. I just neede to specify the PATH as an arg to the function...

Gotta learn to read ALL the words.

Haha, that happens to too many of the best of us. It is awesome that you were re-re-re-reading the man pages. This shows that you are interested in finding the answer not just having someone here give it to you.
