Command Line Functions #

Shell functions #

Standard syntactic forms:

function name {
    commands
    return
}

or

name () {
    commands
    return
}

Local variables #

Shell functions can have local variables internal to the function itself by prepending the variable with local.

funct_1 () {
    local foo
    foo = "something"
    echo "$foo"
}

In your .bashrc #

Neat little trick: putt a shell function in your .bashrc file for custom little functions to be used at the command line.
