Works in Ubuntu, I hope it will work on all Linux machines. For Unixes, tail should be capable of handling more than one file with '-f' option. This command line simply take log files which are text files, and not ending with a number, and it will continuously monitor those files. Putting one alias in .profile will be more useful.
6find /var/log -type f -exec file {} \; | grep 'text' | cut -d' ' -f1 | sed -e's/:$//g' | grep -v '[0-9]$' | xargs tail -f -

Ever compress a file for the web by replacing all newline characters with nothing so it makes one nice big blob? It is a great idea, however what about when you want to edit that file? ...Serious pain in the butt. I ran into this today in that my only copy of a CSS file was "compressed" with no newlines. I whipped this up and it converted back into nice human readable CSS :-) It could be nicer, but it does the job.
1cat somefile.css | awk '{gsub(/{|}|;/,"&\n"); print}' >> uncompressed.css -

With this command you can get a previous or future date or time. Where can you use this? How about finding all files modified or created in the last 5 mins? touch -t `echo $(date -d "5 minute ago" "+%G%m%d%H%M.%S")` me && find . -type f -newer me List all directories created since last week? touch -t `echo $(date -d "1 week ago" "+%G%m%d%H%M.%S")` me && find . -type d -cnewer me I'm sure you can think of more ways to use it. Requires coreutils package. Show Sample Output
5date -d '1 day ago'; date -d '11 hour ago'; date -d '2 hour ago - 3 minute'; date -d '16 hour' -

This will allow you to mount a CD-ROM on Solaris SPARC 9 or lower. This will not work on Solaris 10 due to void and the volume management daemons. www.fir3net.com
-2mkdir -p /cdrom/unnamed_cdrom ; mount -F hsfs -o ro `ls -al /dev/sr* |awk '{print "/dev/" $11}'` /cdrom/unnamed_cdrom -
To sort hidden files first, simply switch the two inner `ls` commands. I have this aliased to `dira` `dir` is aliased to the simpler version with no hidden files:
ls -l --color=always | less -R2less -Rf <( cat <(ls -l --color=always) <(ls -ld --color=always .*) ) -
unzips all zip files in any subdirectory under the current directory. The zip files are unzipped in their respective subdirs
-3for f in `find ./ -name "*.zip"` ; do p=`pwd`; d=`dirname $f`; cd $d; b=`basename $f`; unzip $b; cd $p; done -
Really only valuable in a PHP-only project directory. This is using standard linux versions of the tools. On most older BSD variants of sed, use -E instead of -r. Or use: sed 's/\+[[:space:]]\{1,\}//' instead. Show Sample Output
0for i in `svn status | egrep '^(M|A)' | sed -r 's/\+\s+//' | awk '{ print $2 }'` ; do if [ ! -d $i ] ; then php -l $i ; fi ; done -

The -d flag sets the lifetime of a metric and defaults to 0 hence why old metrics continue to be graphed in the dashboard. Submitting a dummy value and short lifetime ensures that the metric is removed from the dashboard.

This appends a random number as a first filed of all lines in SOMEFILE then sorts by the first column and finally cuts of the random numbers.

Sometimes jittery data hides trends, performing a rolling average can give a clearer view.
3awk 'BEGIN{size=5} {mod=NR%size; if(NR<=size){count++}else{sum-=array[mod]};sum+=$1;array[mod]=$1;print sum/count}' file.dat - ‹ First < 488 489 490 491 492 > Last ›
