Run this within a steady screen session.

You can get the approximate time when the remote server went down or other abnormal behavior.

This will, for an application that has already been removed but had its configuration left behind, purge that configuration from the system. To test it out first, you can remove the last -y, and it will show you what it will purge without actually doing it. I mean it never hurts to check first, "just in case." ;)

User: flatcap
Functions: cmp echo sed

Are the two strings anagrams of one another?

sed splits up the strings into one character per line

the result is sorted

cmp compares the results

Note: This is not pretty. I just wanted to see if I could do it in bash.

Note: It uses fewer characters than the perl version :-)

CHANGELOG

Version 1.1

removedir () { echo "You are about to delete the current directory $PWD Are you sure?"; read human; if [[ "$human" = "yes" ]]; then blah=$(echo "$PWD" | sed 's/ /\\ /g'); foo=$(basename "$blah"); rm -Rf ../$foo/ && cd ..; else echo "I'm watching you" | pv -qL 10; fi; }

BUG FIX:

Folders with spaces

Version 1.0

removedir () { echo "You are about to delete the current directory $PWD Are you sure?"; read human; if [[ "$human" = "yes" ]]; then blah=`basename $PWD`; rm -Rf ../$blah/ && cd ..; else echo "I'm watching you" | pv -qL 10; fi; }

BUG FIX:

Hidden directories (.dotdirectory)

Version 0.9

rmdir () { echo "You are about to delete the current directory $PWD. Are you sure?"; read human; if [[ "$human" = "yes" ]]; then blah=`basename $PWD`; rm -Rf ../$blah/ && cd ..; else echo "I'm watching you" | pv -qL 10; fi; }

Removes current directory with recursive and force flags plus basic human check. When prompted type yes

1. [user@host ~]$ ls

foo bar

2. [user@host ~]$ cd foo

3. [user@host foo]$ removedir

4. yes

5. rm -Rf foo/

6. [user@host ~]$

7. [user@host ~]$ ls

bar

tail would be considered dull, but pair this with being able to push out unix commands over ARD, and life gets easier. (Same can be said for my TimeMachine scrape command, http://xrl.us/begrzb)

find . -maxdepth 1 -iname ".*" | awk 'NR >= 2'

Can be used to list only dotfiles without . nor ..

(cd /bin; set -- *; x=$((1+($RANDOM % $#))); man ${!x})

Very similar but no use of `tr` for

function liner() {

local num_lines=${1:-42}

local line=$(printf %${num_lines}s)

echo ${line// /#}

}

v () { echo "$@"; "$@"; }

Functions: echo

You can use this in shell scripts to show which commands are actually run. Just prepend every "critical line" with "v˽".

$TMP=/tmp

echo "Let me create a directory for you"

v mkdir $TMP/new

In scripts this can be more useful than "set -x", because that can be very verbose with variable assignments etc.

Another nice use is if you prepend every "critical" command with "v", then you can test your script by commenting out the actual execution.

Functions: head sed uuencode

This uses urandom to produce a random password. The random values are uuencoded to ensure only printable characters. This only works for a number of characters between 1 and 60.

This command defragment the SQLite databases found in the home folder of the current Windows user.

This is usefull to speed up Firefox startup.

The executable sqlite3.exe must be located in PATH or in the current folder.

In a script use:

for /f "delims==" %%a in (' dir "%USERPROFILE%\*.sqlite" /s/b ') do echo vacuum;|"sqlite3.exe" "%%a"

This is a quick hack to make a gcc caller. Since it runs with gcc instead of tcc, it's a bit more trustworthy as far as the final answers of things go.
