9. Configuring
Your sysadm has already provided you with a number of configuration files
like .xinitrc, .bash_profile, .inputrc, and many others. The
ones you may want to edit are:
.bash_profile or .profile: read by the shell at login
time. It's like LOGIN.COM;
.bash_logout: read by the shell at logout. It's like
LOGOUT.COM;
.bashrc: read by non--login shells.
.inputrc: this file customises the key bindings and the
behaviour of the shell.
To give you an example, I'll include my .bash_profile (abridged):
# $HOME/.bash_profile
# don't redefine the path if not necessary
echo $PATH | grep $LOGNAME > /dev/null
if [ $? != 0 ]
then
export PATH="$PATH:/home/$LOGNAME/bin" # add my dir to the PATH
fi
export PS1='LOGNAME:\w\$ '
export PS2='Continued...>'
# aliases
alias bin="cd ~/bin" ; alias cp="cp -i" ; alias d="dir"
alias del="delete" ; alias dir="/bin/ls $LS_OPTIONS --format=vertical"
alias ed="jed" ; alias mv='mv -i'
alias u="cd .." ; alias undel="undelete"
# A few useful functions
inst() # Install a .tar.gz archive in current directory.
{
gzip -dc $1 | tar xvf -
}
cz() # List the contents of a .zip archive.
{
unzip -l $*
}
ctgz() # List the contents of a .tar.gz archive.
{
for file in $* ; do
gzip -dc ${file} | tar tf -
done
}
tgz() # Create a .tgz archive a la zip.
{
name=$1 ; tar -cvf $1 ; shift
tar -rf ${name} $* ; gzip -S .tgz ${name}
} |
And this is my .inputrc:
# $HOME/.inputrc
# Last modified: 16 January 1997.
#
# This file is read by bash and defines key bindings to be used by the shell;
# what follows fixes the keys END, HOME, and DELETE, plus accented letters.
# For more information, man readline.
