# User specific aliases and functions

# Execute system startup script:
if [ -f /etc/profile ]
then
  . /etc/profile
fi

# Define primary prompt (default is '$'):
export PS1='[\u@\h:\w] ' # \w shows absolute path, \W shows current folder.

# Always use ssh to connect to CVS repositories:
export CVS_RSH=ssh

# Define PATH:
# Note 1: Do not export PATH, because 
# 1. it is defined in startup script, so every shell gets it!
# 2. only shell needs this variable, other programs normally don't need it.
# Note 2: Add current directory to PATH is dangerous!
#if [ -e ~/bin/addpath.sh ]  then 
#  . ~/bin/addpath.sh ~/bin
#fi

# Define aliases:

# Think twice before deletion. Though troublesome but strongly recommended!
alias rm='rm -i'

# Request X tunneling for SSH:
alias ssh='ssh -C -X'

# Do not verify Host Key change:
alias sshtrust='ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no'

# Always use compression for CVS:
alias cvs='cvs -z9'

alias ps='ps -elf'

alias emacst='emacs -nw'

alias myip='ifconfig | grep netmask'
