How can I set the current working directory to the directory of the script in Bash?

Reliable way for a Bash script to get the full path to itself [duplicate]
Here’s what I’ve come up with (edit: plus some tweaks provided by sfstewman, levigroker, Kyle Strand, and Rob Kennedy), that seems to mostly fit my “better” criteria: SCRIPTPATH=”$( cd — “$(dirname “$0″)” >/dev/null 2>&1 ; pwd -P )” That SCRIPTPATH line seems particularly roundabout, but we need it rather than SCRIPTPATH=`pwd` in order to properly … Read more
Setting environment variables on OS X
Bruno is right on track. I’ve done extensive research and if you want to set variables that are available in all GUI applications, your only option is /etc/launchd.conf.

How to use glob() to find files recursively?
pathlib.Path.rglob Use pathlib.Path.rglob from the the pathlib module, which was introduced in Python 3.5. from pathlib import Path for path in Path(‘src’).rglob(‘*.c’): print(path.name) If you don’t want to use pathlib, use can use glob.glob(‘**/*.c’), but don’t forget to pass in the recursive keyword parameter and it will use inordinate amount of time on large directories. … Read more

mkdir -p functionality in Python [duplicate]
For Python ≥ 3.5, use pathlib.Path.mkdir: import pathlib pathlib.Path(“/tmp/path/to/desired/directory”).mkdir(parents=True, exist_ok=True) The exist_ok parameter was added in Python 3.5. For Python ≥ 3.2, os.makedirs has an optional third argument exist_ok that, when True, enables the mkdir -p functionality—unless mode is provided and the existing directory has different permissions than the intended ones; in that case, OSError … Read more
How to permanently set $PATH on Linux/Unix [closed]

Path.Combine for URLs?
Uri has a constructor that should do this for you: new Uri(Uri baseUri, string relativeUri) Here’s an example: Uri baseUri = new Uri(“http://www.contoso.com”); Uri myUri = new Uri(baseUri, “catalog/shownew.htm”); Note from editor: Beware, this method does not work as expected. It can cut part of baseUri in some cases. See comments and other answers.
