implement the command ls -la |grep <arg> |wc using c language
Posted on 2004-04-19
hi i want to ask how can i implement a program using c language that will emulate a command of the form
ls -la |grep <arg> |wc, where arg is the argument passed to the program at command line.(one argument only)
the output of the program must match with the output of the shell when you type this command at the prompt. i have to create my own .c source file, as well as the makefile which must produce a binary(i.e. executable file) named lgw when make is typed.
note that i should not use the "system" function in my code.
