Linux Shell Tip

Here’s an interesting short cut that I never knew “^” and “!” in linux shell.
It’s an interesting short cut, but it going to need some getting used to.

Tip: ^ and ! in the shell
I’m astounded. So don’t people know about using ^ and ! in the shell?!? Last week I watched an experienced Linux user carefully hit the ↑ cursor key to get a previous line of history, then ←&→ just to make a simple edit!
Here’s my 30 second guide:
!! |
Repeat the previous command. Example:
$ ls bin d Desktop rpmbuild tmp $ !! ls bin d Desktop rpmbuild tmp |
|---|---|
!-2 (etc) |
Repeat the command 2 previously (so !! = !-1), or for any number previously. This is the most useful I think. |
^foo^bar |
Replace foo with bar in the previous command. eg:
$ ls -l /etx/httpd/conf.d/local.conf ls: cannot access /etx/httpd/conf.d/local.conf: No such file or directory $ ^etx^etc ls -l /etc/httpd/conf.d/local.conf -rw-r--r-- 1 root root 76 2009-07-16 14:59 /etc/httpd/conf.d/local.conf |
!foo |
Run the most recent command that started foo, eg:
$ !ls ls -l /etc/httpd/conf.d/local.conf -rw-r--r-- 1 root root 76 2009-07-16 14:59 /etc/httpd/conf.d/local.conf |
Today I discovered that these are called event designators. When I first saw someone using them it was on an Apollo workstation circa 1991, and I pretty quickly picked these up myself.

Debian LAMP Install command
by admin on Sep.24, 2009, under computer, linux, server
Haven’t really touched my home server in a while but planning some upgrade both hardware and software. Including a basic LAMP server.
In order to do this, simply copy and paste following command line for Debian etch
apt-get update apt-get install apache2 libapache2-mod-php5 php5 php5-cli php5-mysql php5-gd php5-mcrypt mysql-client mysql-server libmysqlclient15-dev phpmyadmin
and follow relevant steps to configure apache, mysql and phpmyadmin and secure it before putting online.
