I'm having a hard time trying to remove the colons in a list of MAC addresses.
My file:
00:21:5A:28:62:BF
00:24:81:0A:04:44
Expected Output:
00215A2862BF
0024810A0444
Any ideas on how could I do this? Thanks a lot in advance.

Given your tags, you want to accomplish this in a shell:
cat file | sed s/://g
edit: you don't really need the cat either if you are reading from a file:
sed s/://g file

Isn't that a useless use of cat? sed s/://g file would work just as well without having to invoke another process. See http://partmaps.org/era/unix/award.html

If you want to edit the file in place, just add the `-i` option to the sed command: `sed -i s/://g file` which will alter the file in place rather than printing the result.

Using both -n and -p is pointless. They do the same thing, except -p prints after executing the code, while -n does not.

A:
tr -d ':' < file
will probably work too, though I don't have a command line handy to check the syntax.
