Hai,

How to get all the linux commands in a text file

Hmm, something like:

Code:

apropos .

gives a listing of commands and brief explanation.

Code:

apropos . > file

puts it into a file

Other ways might be:

Code:

ls /usr/bin
ls /usr/sbin/

You might want to filter out command-line items only - "apropos ." will list manual pages for C library calls and file formats and system calls etc... Try this:

Code:

apropos . | fgrep "(1)" > file

or

Code:

(IFS=:;ls -1 $PATH)

Here's my attempt. It's a little more complicated but easier on my eyes. If you run it as a regular user vs. root, you will get different results (assuming that you have different paths which you will on most systems).

Code:

#!/usr/bin/perl
use strict;
use warnings;
 
chomp(my @path = split (":", `echo \$PATH`));
 
foreach my $directory (@path) {
     print "Items in $directory:\n";
     chdir "$directory"
         or die "Can't chdir to $directory: $!\n";
     print map { "\t$_\n" } grep { -x $_ } glob "*" ;
}
