This pipeline will find, sort and display all files based on mtime. This could be done with find | xargs, but the find | xargs pipeline will not produce correct results if the results of find are greater than xargs command line buffer. If the xargs buffer fills, xargs processes the find results in more than one batch which is not compatible with sorting.

Note the "-print0" on find and "-0" switch for perl. This is the equivalent of using xargs. Don't you love perl?

Note that this pipeline can be easily modified to any data produced by perl's stat operator. eg, you could sort on size, hard links, creation time, etc. Look at stat and just change the '9' to what you want. Changing the '9' to a '7' for example will sort by file size. A '3' sorts by number of links....

Use head and tail at the end of the pipeline to get oldest files or most recent. Use awk or perl -wnla for further processing. Since there is a tab between the two fields, it is very easy to process.

This dup finder saves time by comparing size first, then md5sum, it doesn't delete anything, just lists them.

This command dumps all SVN repositories inside of folder "repMainPath" (not recursively) to the folder "dumpPath", where one dump file will be created for each SVN repository.

Same thing, only "head" instead of grep/egrep..

Useful for backing up old files, custom logs, etc. via a cronjob.

you must be in the directory to analyse

report all files and links in the currect directory, not recursively.

this find command ahs been tested on hp-ux/linux/aix/solaris.

A little bit smaller, faster and should handle files with special characters in the name.

This can be much faster than downloading one or both trees to a common servers and comparing the files there. After, only those files could be copied down for deeper comparison if needed.

search argument in PATH

accept grep expressions

without args, list all binaries found in PATH

OS: Debian based (or those that use dpkg)

Equivalent to doing a dpkg -S on each file in $PATH, but way faster.

May report files generated though postinstall scripts and such. For example . It will report /usr/bin/vim .. which is not not a file installed directly by dpkg, but a link generated by alternatives hooks

This is really fast :)

Lists out all classes used in all *.html files in the currect directory. usefull for checking if you have left out any style definitions, or accidentally given a different name than you intended. ( I have an ugly habit of accidentally substituting camelCase instead of using under_scores: i would name soemthing counterBox instead of counter_box)

WARNING: assumes you give classnames in between double quotes, and that you apply only one class per element.

This is the way how you can find header and cpp files in the same time.

Put the positive clauses after the '-o' option.

Have wc work on each file then add up the total with awk; get a 43% speed increase on RHEL over using "-exec cat|wc -l" and a 67% increase on my Ubuntu laptop (this is with 10MB of data in 767 files).

Based on the MrMerry one, just add some visuals and sort directory and files

Make sure that find does not touch anything other than regular files, and handles non-standard characters in filenames while passing to xargs.

needs no GNU tools, as far as I see it

For Mac OS X users only

This has helped me numerous times trying to find either log files or tmp files that get created after execution of a command. And really eye opening as to how active a given process really is. Play around with -anewer, -cnewer & -newerXY

get diskusage of files (in this case logfiles in /var/log) modified during the last n days:

n -> last modified n*24 hours ago

Numeric arguments can be specified as

+n for greater than n,

-n for less than n,

n for exactly n.

=> so 7*24 hours (about 7 days) is -7

1. find file greater than 10 MB

2. direct it to xargs

3. xargs pass them as argument to ls
