alias showip="ifconfig eth0 | grep 'inet addr:' | sed 's/.*addr\:\(.*\) Bcast\:.*/\1/'"

alias to show my own configured ip

parses the output of ifconfig to show only the configured ip address (in this case from interface eth0). the regexp is quick'n'dirty im sure it can be done in a better way. --> this alias does not show your "internet ip" when you're in a nat-environment
Sample Output
$ showip
192.168.0.55

  • Creates a command alias ('cr' in the above example) that searches the contents of files matching a set of file extensions (C & C++ source-code in the above example) recursively within the current directory. Search configured to be in colour, ignore-case, show line numbers and show 4 lines of context. Put in shell initialisation file of your choice. Trivially easy to use, e.g: cr sha1_init Show Sample Output

    alias cr='find . 2>/dev/null -regex '\''.*\.\(c\|cpp\|pc\|h\|hpp\|cc\)$'\'' | xargs grep --color=always -ni -C2'

  • Alias a single character 'b' to move to parent directory. Put it into your .bashrc or .profile file. Using "cd .." is one of the most repetitive sequence of characters you'll in the command line. Bring it down to two keys 'b' and 'enter'. It stands for "back" Also useful to have multiple: alias b='cd ../' alias bb='cd ../../' alias bbb='cd ../../../' alias bbbb='cd ../../../../' Show Sample Output


    1
    alias b='cd ../'

  • Put the function in your .bashrc and use "map [alias]" to create the alias you want. Just be careful to not override an existing alias. Show Sample Output

    map() { if [ "$1" != "" ]; then alias $1="cd `pwd`"; fi }

  • some configuration files, particularly those installed by default as part of a package, have tons of comment lines, to help you know what's possible to configure, and what it means. That's nice, but sometimes you just want to see what specifically what _has_ been configured. That's when I use the above snippet, which I save as a bash alias 'nocom' (for 'no comments'). Apache default config files are perfect examples of when/why this script is handy.

and if we have two (or more) active network interfaces?
mpb · 477 weeks and 4 days ago
ifconfig $if | egrep -o "inet addr:[^ ]*"
bandie91 · 477 weeks and 4 days ago
Assuming that the default route is via the network interface of interest: /sbin/ifconfig $(netstat -rn | grep "^0.0.0.0" | awk '{print $8}') | awk -F: '/inet addr/ {printf("%s\n",substr($2,1,index($2," "))) }'
mpb · 477 weeks and 4 days ago
there must be a simpler way to do this...
elzapp · 477 weeks and 4 days ago
ifconfig $(route|grep default|awk '{ print $8 }')|grep 'inet addr:' | sed 's/.*addr\:\(.*\) Bcast\:.*/\1/' to show ip of default route
