How to install:

Top reasons to use ack instead of grep.

• It's blazingly fast because it only searches the stuff you want searched.
• ack is pure Perl, so it runs on Windows just fine.
• The standalone version uses no non-standard modules, so you can put it in your ~/bin without fear.
• Searches recursively through directories by default, while ignoring .svn, CVS and other VCS directories.
  • Which would you rather type?
  • $ grep pattern $(find . -type f | grep -v '\.svn')
  • $ ack pattern
• ack ignores most of the crap you don't want to search
  
  • VCS directories
  • blib, the Perl build directory
  • backup files like foo~ and #foo#
  • binary files, core dumps, etc
• Ignoring .svn directories means that ack is faster than grep for searching through trees
• Lets you specify file types to search, as in --perl or --nohtml
  
  • Which would you rather type?
  • $ grep pattern $(find . -name '*.pl' -or -name '*.pm' -or -name '*.pod' | grep -v .svn)
  • $ ack --perl pattern
  • Note that ack's --perl also checks the shebang lines of files without suffixes, which the find command will not
• File-filtering capabilities usable without searching with ack -f. This lets you create lists of files of a given type
  
  • $ ack -f --perl > all-perl-files
• Color highlighting of search results

If you have to admin Aleph from ExLibris you may be wondering why there is minimal tools to help you make sure its all running ok

Below is a simple shell script that checks various 'ue_' process (PC server, publishing, etc..) and emails if they are down

Add this to your crontab to run each 15 minutes or so

Note:
- replace the email address with your email address
- replace LIB with your 3 character library code
- add/remove ue_ sections as you need

#!/bin/bash

this will allow Ctrl+PageUp/Down to work to switch tabs

if you want to use Alt+Up/Down add the below in

map <M-up> :tabprevious<CR> 
map <M-down> :tabnext<CR>

 
# Arrow keys to switch terminals (only works with X) 
# Alt + left 
bindkey ^[[1;3D prev 
# Alt + right 
bindkey ^[[1;3C next 

note:
- not use Ctrl + Alt + Left/Rigth Arrow as its used by GNOME to swap
virtual desktops
- nor firefox style as its used by GNOME Terminal for switching its tabs
- to find out what Alt/Fn/Ctrl characters equal what just execute cat
and start typing

Creating the file:

vi passwords.txt

Encrypt the file:

gpg -c -a passwords.txt

rm passwords.txt

gpg -d passwords.txt.asc | less

gpg passwords.txt.asc

simple example to send an email if $message is not null

 
SUBJECT="Automated Security Alert" 
TO="alarms@someaddress.com" 
 
$message '' # if error or alert then create a message 
 
if [[ -n $message ]] 
then 
 echo $message 
 /bin/mail -s "$SUBJECT" "$TO"

to check if a string is null

 
 String='' # Zero-length ("null") string variable. 
 
if [ -z "$String" ] 
then 
 echo "\$String is null." 
else 
 echo "\$String is NOT null." 
fi # $String is null.
