Here is an example of a function that creates a directory and cd s into it. Unlike other scripting languages, bash uses a variety of special variables to refer to arguments, error codes, and other relevant variables.
Below is a list of some of them. A more comprehensive list can be found here. A value of 0 usually means everything went OK; anything different from 0 means an error occurred. Commands can also be separated within the same line using a semicolon ;.
The true program will always have a 0 return code and the false command will always have a 1 return code. Another common pattern is wanting to get the output of a command as a variable. This can be done with command substitution. Bash implements many comparisons of this sort - you can find a detailed list in the manpage for test. When performing comparisons in bash, try to use double brackets [[ ]] in favor of simple brackets [ ].
A more detailed explanation can be found here. When launching scripts, you will often want to provide arguments that are similar. Bash has ways of making this easier, expanding expressions by carrying out filename expansion. These techniques are often referred to as shell globbing.
Writing bash scripts can be tricky and unintuitive. Note that scripts need not necessarily be written in bash to be called from the terminal. The kernel knows to execute this script with a python interpreter instead of a shell command because we included a shebang line at the top of the script. It is good practice to write shebang lines using the env command that will resolve to wherever the command lives in the system, increasing the portability of your scripts.
To resolve the location, env will make use of the PATH environment variable we introduced in the first lecture. For this example the shebang line would look like! At this point, you might be wondering how to find the flags for the commands in the aliasing section such as ls -l , mv -i and mkdir -p. More generally, given a command, how do you go about finding out what it does and its different options?
You could always start googling, but since UNIX predates StackOverflow, there are built-in ways of getting this information. As we saw in the shell lecture, the first-order approach is to call said command with the -h or --help flags. A more detailed approach is to use the man command. Short for manual, man provides a manual page called manpage for a command you specify.
