Thank you for this answers Smilie

By the way, do you also have a magic command to remove lines that are longer or smaller than a number ?

For instance remove all the lines in a file that are longer than 20 caracters, remove others that are smaller than 5 caracters, etc.

Thank you Smilie

NAME
remove - remove file SYNOPSIS
#include <stdio.h> int remove(const char *path); DESCRIPTION
The remove() function causes the file or empty directory whose name is the string pointed to by path to be no longer accessible by that name. A subsequent attempt to open that file using that name will fail, unless the file is created anew. For files, remove() is identical to unlink(). For directories, remove() is identical to rmdir(). See rmdir(2) and unlink(2) for a detailed list of failure conditions. RETURN VALUES
Upon successful completion, remove() returns 0. Otherwise, it returns -1 and sets errno to indicate an error. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+ SEE ALSO
