These are for cases where you know that the directory contains only regular files and that you want to process all non-hidden files. If that is not the case, use the approaches in 2.

All sed solutions in this answer assume GNU sed. If using FreeBSD or macOS, replace -i with -i ''. Also note that the use of the -i switch with any version of sed has certain filesystem security implications and is inadvisable in any script which you plan to distribute in any way.

Non recursive, files in this directory only:

 sed -i -- 's/foo/bar/g' *
 perl -i -pe 's/foo/bar/g' ./* 
(the perl one will fail for file names ending in | or space)).

Here are several different ways to test a TCP port without telnet.

BASH (man page)

$ cat < /dev/tcp/127.0.0.1/22
SSH-2.0-OpenSSH_5.3
^C

$ cat &lt; /dev/tcp/127.0.0.1/23

echo '<14>_sourcehost_ messagetext' | nc -v -u -w 2 _desthost_ 514

Example:
echo '<14>192.168.0.5 messagetext' | nc -v -u -w 2 192.168.0.105 514
