ip link | grep 'link/ether' | awk '{print $2}'

User: markdrago
Functions: awk grep link
Tags: mac

I much prefer using /sbin/ip over /sbin/ifconfig for most everything. I find the interface and output to be much more consistent and it has many abilities that ifconfig, route, etc. do not. To get the mac address for only one interface, add 'show dev [interface]' to the 'ip link' part of the command: ip link show dev eth0 | grep 'link/ether' | awk '{print $2}' . Also, both this command and the ifconfig one do not require root access to run, so the sudo is not necessary.

Sometimes, you don't really care about all the other information that ifconfig spits at you (however useful it may otherwise be). You just want an IP. This strips out all the crap and gives you exactly what you want.

besure to adjust your find to use to correct location of your VMX files.

find . -name '*.java' | xargs -L 1 cpp -fpreprocessed | grep . | wc -l
2009-10-29 09:58:43
User: rbossy
Functions: cpp find grep wc xargs

I took java to make the find command simpler and to state that it works for any language supported by cpp.

cpp is the C/C++ preprocessor (interprets macros, removes comments, inserts includes, resolves trigraphs). The -fpreprocessor option tells cpp to assume the input has already been preprocessed so it will only replace comment lines with blank lines.

The -L 1 option tells xargs to launch one process for each line, indeed cpp can only process one file at the time...

You can use -e to pass multiple patterns.

grep 'test' somefile | grep -vE '(error|critical|warning)'

User: zlemini
Functions: grep

Use multiple patterns with grep -v. So you can print all lines in a file except those containing the multiple patterns you specify.

ord () { seq 1 127 | while read i; do echo `chr $i` $i; done | grep "^$1 " | cut -c '3-' }
2009-10-16 21:54:01
User: infinull
Functions: cut echo grep read seq

uses the previous "chr" function and uses it to create the inverse function "ord" by brute force.

It's slow, It's inelegant, but it works.

I thought I needed ord/chr to do a cartesian cipher in shell script a whie ago, but eventualy I realized I could get fancy with tr and do the same thing...

Tags: bash grep

Place this in your .bash_profile and you can use it two different ways. If you issue 'h' on its own, then it acts like the history command. If you issue:

h cd

Then it will display all the history with the word 'cd'

No need for -l and the output can be sent directly into another function expecting directory names.

Functions: dirname find grep info sed xargs

Searches for all .project files in current folder and below and uses "svn info" to get the last changed revision. The last sed joins every two lines.
