Vis mig dine bedste .bashrc funktioner/alias's

Goddag alle sammen!

I stedet for alle disse diskussioner hvor vi skal afgrænse vort system i forhold til de andre alternativer vil jeg gerne diskutere et aspekt, som jeg personligt er blevet meget glad for. Nemlig evnen til at definere bash alias's og funktioner til at udvide ens shell.

Jeg håber at i også viser mig jeres .bashrc alias's/funktioner så vi måske alle sammen kan samle et par gode shortcuts op.

Nuvel, her er mine:

echo "Custom alias' loaded"

#coloured file listings
alias ls="ls --color"

#short-hand for automatically discovering newly added files
#and formally adding them to the actual svn repo:
alias svn_addnew="svn status| grep '^?' | awk -F ' ' '{print $2}' | tr '\n' '\0' | xargs -0 svn add"

# short-hand for grepping history (usage: greph COMMAND)
alias greph="history | grep "

#short-hand for connecting to my home-server
alias ssh_srv="ssh -i /home/icarus/.ssh/.id_server -p 22 icarus@xxx.xxx.xxx.xxx"

# Displays free ram in MB
alias ramfree="free -m|grep '\-/+'|tr -s ' '|cut -d' ' -f4 --output-delimiter=\n|xargs -I {} echo '{} MB'"

#Displays used ram in MB
alias ramused="free -m|grep '\-/+'|tr -s ' '|cut -d' ' -f3 --output-delimiter=\n|xargs -I {} echo '{} MB'"

#Displays the sizes of all files/directories in the current directory
alias filesizes="ls --color -la --block-size=1048576| grep ^-|tr -s \" \"|cut -d\" \" -f5,8| sed 's/[0-9]*/&MB\t/'"

#Will continuously output information about traffic going on at the supplied port
monitor_traffic() {
EXPECTED_ARGS=2
if [ $# -ne $EXPECTED_ARGS ]
then
echo "Usage: monitor_traffic {iface} {port}"
return
fi
sudo tcpdump -lnn -i $1 port $2
}

#Saves a list of the currently installed packages and instructs users how
# to use it to install the same package set on other pc's (or in a reinstall)
pkglist_save() {
EXPECTED_ARGS=1
if [ $# -ne $EXPECTED_ARGS ]
then
echo "Usage: pkglist_save {outout_file}"
return
fi
dpkg --get-selections|grep -v deinstall > $1
echo "list of installed packages saved to '$1'"
echo "restore using 'pkglist_install $1'"
}

# Takes a file with dpkg-selections and install whatever packages we don't already have.
pkglist_install() {
EXPECTED_ARGS=1
if [ $# -ne $EXPECTED_ARGS ]
then
echo "Usage: pkglist_install {pkglist file}"
return
fi
sudo apt-get update
sudo apt-get dist-upgrade
sudo dpkg --set-selections < $1
sudo apt-get -u dselect-upgrade
}

#lists all the ports of traffic currently open to the internet
alias openports="netstat --nape --inet"

#Connect to a wireless network using WPA
conn_wpa() {
EXPECTED_ARGS=3
if [ $# -ne $EXPECTED_ARGS ]
then
echo "Usage: conn_wpa {iface} {essid} {passphrase}"
return

echo "Connecting to network '$2' on interface '$1' using passphrase '$3'"
wpa_passphrase $2 $3 > /tmp/conn_wpa.conf
sudo wpa_supplicant -B -i $1 -Dwext -c /tmp/conn_wpa.conf
sudo dhclient $1
}

#Connect to a wireless network using WEP
conn_wep() {
EXPECTED_ARGS=3
if [ $# -ne $EXPECTED_ARGS ]
then
echo "Usage: conn_wep {iface} {essid} {key}"
return
fi
echo "Connecting to network '$2' on interface '$1' using key $3"
sudo iwconfig $1 essid $2 key s:$3
sudo dchlient $1
}

# Just a more sensible name for a tool which outputs information about the network interface
link_status() {
EXPECTED_ARGS=1
if [ $# -ne $EXPECTED_ARGS ]
then
echo "Usage: link_status {interface}"
echo "Displays status information abount a (wired) network interface"
return

mii-tool -v $1
}


Som man kan se er de fleste af mine funktioner en form for "convenience" funktioner. Fx er "filesizes" blot en måde hvorpå jeg ikke skal huske hvad 1024*1024 (for at få bytes til MB) giver etc.

Nuvel, hvad har i liggende af "genveje" i bashrc ? :)
