macOS If statements in shell

[lynkynpark86]

Does anyone know how I would do this in a shell script?
If x is a file: somecommand
If x is a directory: someothercommand

 

[throAU]

Which shell? sh? csh?

edit:

you could use "test".

read

man test

 

[dmi]

test -f x && somecommand
test -d x && someothercommand

[ is an alias for test, which is quite funny I think. 😀 Try: man [ it will bring up the manual for test. It gives a bit more syntactically pleasing look if used in a script.

if [ -f $1 ]
then
    echo file
else if [ -d $1 ]
    echo directory
fi

Aha, it's: The Linux Documentation Project. Not: Too Long Didn't P*.

FWIW, there are also the shell builtins [[ and ]], via 'man bash'. Somewhat different syntax for the expressions, but otherwise the same as test and [ (which are also bash builtins).

 

[dmi]

test and [ are /bin utilities, which would work in all shells
[[ ... ]] is a bash (and ksh) built in

 

[chown33]

[[ ... ]] is a bash (and ksh) built in

FWIW, test and [ are bash builtins. They also exist as /bin tools, but bash (like other shells) searches its builtins first, unless the command contains a slash.

Try this:

type [ test

type is another builtin, otherwise similar to which (which isn't a builtin in bash).
