Check These Out

Move a folder and merge it with another folder
This will move a folder and merge it with another folder which may contain duplicates. Technically it's just creating hardlinks of everything in the folder, and after it's done, delete the source (with rm -r source/ ) to complete the move. This is much faster than, for example, using rsync to merge folders which would actually copy the entire contents and so for a lot of files would take much longer. This uses macutils gcp port of cp so it can be used on osx/MacOS. If using in linux or some unix where cp includes the ability to create links with -l you can just use cp instead of gcp.

vmstat/iostat with timestamp
Also useful with iostat, or pretty much anything else you want timestamped.

Python extract json

Check host port access using only Bash:

Convert a file from ISO-8859-1 (or whatever) to UTF-8 (or whatever)
I use it sometimes when I work on a french file transferred from a windows XP to a Debian-UTF8 system. Those are not correctly displayed: ? ? ? and so on $man tcs # for all charsets

draw mesh

ssh tunnel with auto reconnect ability

Debug your makefile
Say your dependencies specified in your Makefile (or dates on your source files) is causing 'make' to skip some source-files (that it should not) or on the other other end, if it is causing make to always build some source-files regardless of dates of target, then above command is handy to find out what 'make' thinks of your date v/s target date-wise or what dependencies are in make's view-point. The egrep part removes the extra noise, that you might want to avoid.

Unzip multiple files with one command
With this command you can easily unzip multiple zip files with just one command. All you need to do is to use single quotes.

Get all IPs via ifconfig
and, a lot uglier, with sed: $ ifconfig | sed -n '/inet addr:/s/[^:]\+:\(\S\+\).*/\1/p' Edit: Wanted to be shorter than the perl version. Still think that the perl version is the best..
