Over the weekend I got into some bash functions.
Paste these into your .bashrc file
Enjoy
1. Command line wiki query
#wiki
function wiki () {
COLUMNS=`tput cols`
dig +short txt “`echo $@`”.wp.dg.cx | sed -e ‘s/” “//g’ -e ‘s/^”//g’ -e ‘s/”$//g’ -e ‘s/ http:/\n\nhttp:/’ | fmt -w $COLUMNS
}
2. Disk Usage with human readable formatting
#disk usage formatted
function duf {
du -sk "$@" | sort -n | while read size fname; do for unit in k M G T P E Z Y; do if [ $size -lt 1024 ]; then echo -e "${size}${unit}\t${fname}"; break; fi; size=$((size/1024)); done; done
}
3. Directory sizes
#dirsize - finds directory sizes and lists them for the current directory
dirsize () {
du -shx * .[a-zA-Z0-9_]* 2> /dev/null | \
egrep '^ *[0-9.]*[MG]' | sort -n > /tmp/list
egrep '^ *[0-9.]*M' /tmp/list
egrep '^ *[0-9.]*G' /tmp/list
rm -rf /tmp/list
}
4. Power extract function
#extract
extract () {
if [ -f $1 ] ; then
case $1 in
*.tar.bz2) tar xjf $1 ;;
*.tar.gz) tar xzf $1 ;;
*.bz2) bunzip2 $1 ;;
*.rar) rar x $1 ;;
*.gz) gunzip $1 ;;
*.tar) tar xf $1 ;;
*.tbz2) tar xjf $1 ;;
*.tgz) tar xzf $1 ;;
*.zip) unzip $1 ;;
*.Z) uncompress $1 ;;
*.7z) 7z x $1 ;;
*) echo "'$1' cannot be extracted via extract()" ;;
esac
else
echo "'$1' is not a valid file"
fi
}
6. Network Information
#netinfo - shows network information for your system
netinfo ()
{
echo "--------------- Network Information ---------------"
/sbin/ifconfig | awk /'inet addr/ {print $2}'
/sbin/ifconfig | awk /'Bcast/ {print $3}'
/sbin/ifconfig | awk /'inet addr/ {print $4}'
/sbin/ifconfig | awk /'HWaddr/ {print $4,$5}'
myip=`lynx -dump -hiddenlinks=ignore -nolist http://checkip.dyndns.org:8245/ | sed '/^$/d; s/^[ ]*//g; s/[ ]*$//g' `
echo "${myip}"
echo "---------------------------------------------------"
}
7. Translate from commandline
#Translate a Word - USAGE: translate house spanish # See dictionary.com for available languages (there are many).
translate ()
{
TRANSLATED=`lynx -dump "http://dictionary.reference.com/browse/${1}" | grep -i -m 1 -w "${2}:" | sed 's/^[ \t]*//;s/[ \t]*$//'`
if [[ ${#TRANSLATED} != 0 ]] ;then
echo "\"${1}\" in ${TRANSLATED}"
else
echo "Sorry, I can not translate \"${1}\" to ${2}"
fi
}
8. Define a word
# Define a word - USAGE: define dog
define ()
{
lynx -dump "http://www.google.com/search?hl=en&q=define%3A+${1}&btnG=Google+Search" | grep -m 3 -w "*" | sed 's/;/ -/g' | cut -d- -f1 > /tmp/templookup.txt
if [[ -s /tmp/templookup.txt ]] ;then
until ! read response
do
echo "${response}"
done < /tmp/templookup.txt
else
echo "Sorry $USER, I can't find the term \"${1} \""
fi
\rm -f /tmp/templookup.txt
}
9. Simple Clock
# clock - A bash clock that can run in your terminal window.
clock ()
{
while true;do clear;echo "===========";date +"%r";echo "===========";sleep 1;done
}
MORE functions can be found here
Funny ones, thkx.
Anyway for the Extract function i recommend the “atool” python scripts. Very very useful =)
Excellent, however, it’s only 8 insane bash scripts 😉
