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

Once I decided weirdly to combine two commands into a single one with possibility to keep the command line options of the both commands. It was assumed the following:

# original and simple usage
command1 options1 | command2 options2

# modified and weird one
super_command options1 -- options2

Print last starting entries found in all available log files

There are two kinds of magic: black and white. Take one spell:

• Gandalf's formulae use white magic of awk or perl
• Saruman's formulae use black magic trickily blending grep, sed, awk, tac and sort

Description

1. process files FILE_PATTERN
