[COKEDUDE]

Could anyone tell me what "cat foo –" does in unix please? Also where is there documentation about this so I know where to look in the future.

Hello,

Welcome to the ComputerHope Forums.

Generally, foo, foobar, baz, etc are used as placeholders to some arbitrary unknowns. Thus

Code: [Select]

cat foo -might be used as an example usage of cat. The user has to replace it by something valid, according to the condition, a valid filename in this case.
