Command to Show a List of Special Characters for bash prompt (PS1)

I use this command (PS1) to show a list bash prompt's special characters. I tested it against A flavor of Red Hat Linux and Mac OS X Show Sample Output

This is sample output - yours may be different.

$ PS1
              \a     an ASCII bell character (07)
              \d     the  date in "Weekday Month Date" format (e.g., "Tue May

              \D{format}
                     the format is passed to strftime(3) and  the  result  is
                     inserted into the prompt string; an empty format results
                     in a locale-specific time  representation.   The  braces
                     are required
              \e     an ASCII escape character (033)
              \h     the hostname up to the first '.'
              \H     the hostname

              \l     the basename of the shell's terminal device name
              \n     newline
              \r     carriage return
              \s     the  name  of the shell, the basename of $0 (the portion
                     following the final slash)
              \t     the current time in 24-hour HH:MM:SS format
              \T     the current time in 12-hour HH:MM:SS format
              \@     the current time in 12-hour am/pm format
              \A     the current time in 24-hour HH:MM format
              \u     the username of the current user

              \V     the release  of  bash,  version  +  patch  level  (e.g.,
                     2.00.0)
              \w     the  current  working  directory, with $HOME abbreviated
                     with a tilde
              \W     the basename of  the  current  working  directory,  with
                     $HOME abbreviated with a tilde

              \#     the command number of this command
              \$     if the effective UID is 0, a #, otherwise a $
              \nnn   the character corresponding to the octal number nnn
              \\     a backslash
              \[     begin a sequence of non-printing characters, which could
                     be used to embed a terminal control  sequence  into  the
                     prompt
              \]     end a sequence of non-printing characters

Change mysql prompt to be more verbose

You can put this into your shell sourced file like .bashrc or .zshrc to have a different mysql prompt. See http://dev.mysql.com/doc/refman/5.1/de/mysql-commands.html for more informations. Beware that currently with mysql 5.5 the seconds are buggy and won't be displayed if you put this into a .cnf file. With the enironment variable this will work. Show Sample Output
This is sample output - yours may be different.
```
$ mysql -u user database
mysql://user@localhost:/database - 19:15:25 > [you're here]
```

export MYSQL_PS1="mysql://\u@\h:/\d - \R:\m:\s > "

Pretend your shell is MS-DOS command.com

(This may be specific to bash only.) This transforms the current working directory to all uppercase characters and replaces forward slashes with backslashes, prepending the string with "C:" and appending a single ">". It serves no practical purpose, but may serve as a great practical joke if you can insert it to some victim's .bashrc :-) Show Sample Output

export PROMPT_COMMAND=$PROMPT_COMMAND'; export PWD_UPCASE="${PWD^^}"'; export PS1='C:${PWD_UPCASE//\\//\\\\}>'

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Create an eicar.com test virus

Test whether real-time virus detection is working by running this command and checking for eicar.com in /tmp. Requires real-time scanning to be enabled and active on the /tmp directory. If scanning is active, the file should be quarantined/deleted (depending on your settings) moments after running this command. If not, the (harmless) test file should remain in your /tmp directory.

Matrix Style

Print every Nth line

Sometimes commands give you too much feedback. Perhaps 1/100th might be enough. If so, every() is for you. $ my_verbose_command | every 100 will print every 100th line of output. Specifically, it will print lines 100, 200, 300, etc If you use a negative argument it will print the *first* of a block, $ my_verbose_command | every -100 It will print lines 1, 101, 201, 301, etc The function wraps up this useful sed snippet: $ ... | sed -n '0~100p' don't print anything by default $ sed -n starting at line 0, then every hundred lines ( ~100 ) print. $ '0~100p' There's also some bash magic to test if the number is negative: we want character 0, length 1, of variable N. $ ${N:0:1} If it *is* negative, strip off the first character ${N:1} is character 1 onwards (second actual character).

Show most common words in filenames

I'm sure there's a more elegant sed version for the tr + grep section.

Show sections of a man page.

Uses the formatting of a man page to show an outline of its headers and sub-headers.

Find usb device

I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Unzip and untar a *.tar.gz file in one go to a specific directory

A *.tar.gz file needs to be unzipped & then untarred. Previously I might have unzipped first with $gunzip -d file.tar.gz and then untarred the result with $tar -xvf file.tar (Options are extract, verbose, file) Using the -z (decompress) option on tar avoids the use of gzip (or gunzip) first. Additionally the -C option will specify the directory to extract to.
