Problem :
taken from the SED $HOME :
“USE OF ‘\t’ IN SED SCRIPTS: For clarity in documentation, we have used
the expression '\t' to indicate a tab character (0x09) in the scripts. However, most versions of sed do not recognize the '\t' abbreviation, so when typing these scripts from the command line, you should press the TAB key instead. '\t' is supported as a regular expression metacharacter in awk, perl, and HHsed, sedmod, and GNU sed v3.02.80."

System administration in Linux / BSD can never do without a text editor, and vim is definitely de-factor editor. vim is not only an text editor, it can be also a IDE (integrated development environment) and it is extremely light in resource. Just to mention a few of its features, syntax highlighting, auto indent, search & replace, copy/cut & paste & others. vim comes with all versions of linux & BSD, check your flavors documentation.
Problem :
copy / cut text from other apps (e.g. gedit, openoffice, kedit, abiword, textmate, notepad, textedit & other text editor) to vim often jumble up the space.

Traditionally, search and replace in files have to be done in editor. But if the operation involves multiple files, it would not be practical to use editor on every files as it can be tedious (more then 5 files?) and also error prune. By using a few of bash utilities, the task can be achieve with no error and also a great opportunity to learn a few handy bash tools / command. Below is a scenario that commonly needs to be done.
Problem :
Find & replace text from a set of files
Solution :
Most of the time, we need to write a script to update multiple fields in a database table, pull values from database to fill up other tables or even grab from database and pass it to programs to process. The most annoying thing is every time it tries to connect to the database server, it prompts for password. Worse, if the sql statement in the bash script is not optimized or written properly, the scripts could actually ask for the password, more then 1 time !!!
Problem :
Connecting to postgresql (psql) within a bash script with no password, preferred.

Writing script might not be only wants to shows the result on the screen. Some times, we want the script to output to a file. Not only result, but also the errors. Result of cause we want to the know, but errors is valuable also, when we need it to debug the script.
