truncate deleted files from lsof

While the posted solution works, I'm a bit uneasy about the "%d" part. This would be hyper-correct approach: lsof|gawk '$4~/txt/{next};/REG.*$deleted$$/{sub(/.$/,"",$4);printf ">/proc/%s/fd/%s\n", $2,$4}' Oh, and you gotta pipe the result to sh if you want it to actually trim the files. ;) Btw, this approach also removes false negatives (OP's command skips any deleted files with "txt" in their name).

List only the directories

This command would be useful when it is desirable to list only the directories. 'egrep' chooses only the lines that begin with 'd'.

Recursively remove directory with many files quickly

rsync'ing an empty directory over a directory to be deleted recursively is much faster than using rm -rf, for various reasons. Relevant only for directories with really a lot of files.

How many days until the end of the year

add all files not under version control to repository

This should handle whitespaces well and will not get confused if your filenames have "?" in them

Install pip with Proxy

Installs pip packages defining a proxy

Install an mpkg from the command line on OSX

Installing most OSX apps is just a matter of dropping it in /Applications, either GUI-wise or with cp -r. However, many packages are distributed in "mpkg" format, and those have to be installed with an installer. If you don't want to go to the trouble of firing up VNC to install an mpkg, you can use the "installer" command. This will install an application from a .mpkg it to /Applications system-wide. To install a program for just one user, replace "-target /" with "-target username".

Get a Bulleted List of SVN Commits By a User for a Specifc Day (Daily Work Log)

* Replace USERNAME with the desired svn username * Replace the first YYYY-MM-DD with the date you want to get the log (this starts at the midnight event that starts this date) * Replace the second YYYY-MM-DD with the date after you want to get the log (this will end the log scan on midnight of the previous day) Example, if I want the log for December 10, 2010, I would put {2010-12-10}:{2010-12-11}

check open ports without netstat or lsof
