TEST(1)                                                                                        User Commands                                                                                        TEST(1)
NAME
       test - check file types and compare values
NAME
SYNOPSIS
       test EXPRESSIONle types and compare values
       test
       [ EXPRESSION ]
       [ ]
       [ OPTION
...
       Except for -h and -L, all FILE-related tests dereference symbolic links.  Beware that parentheses need to be escaped (e.g., by backslashes) for shells.  INTEGER may also be -l STRING, which evalu‐
       ates to the length of STRING.
       NOTE: [ honors the --help and --version options, but test does not.  test treats each of those as it treats any other nonempty STRING.
       NOTE: your shell may have its own version of test and/or [, which usually supersedes the version described here.  Please refer to your shell's documentation for details about the options  it  sup‐
       ports.
