I've decided to create a post with several recipes for commands I need to use daily. I use them from a Mac OS X Lion default console, except for some mac ports installed... Remote is special linux distribution. How do I Compress a Whole Linux or UNIX Directory?  You need to use tar command as follows (syntax of tar command): tar -zcvf archive-name.tar.gz directory-name Where, -z: Compress archive using gzip program -c: Create archive -v: Verbose i.e display progress while creating archive -f: Archive File name For example, you have directory called /home/garmoncheg/data and you would like to compress this directory then you can type tar command as follows: $ tar - zcvf data . tar . gz / home / garmoncheg / data / Above command will create an archive file called data.tar.gz in current directory.

We often get strange errors with python. When you changing the source and cannot figure out why files are used from past. So if you ever get this dejavu feeling, try using this command: find . -type f -name '*.pyc' -exec rm {} \; It will delete all precompiled python sources. (Because with python you have ability to distribute your files in binaries in fact.) Those errors usually appear if you move/delete *.py files with version control. You usually exclude *.pyc files from list. Old links used this way. Debugger does not suggest wrong imports because your files are in fact there, just precompiled. Anyway I've just put this command to my blog for memorizing. It often helps me. Maybe it can for you.
