NAME
test - Check file types and compare values.
SYNOPSIS
test [-h|--help] [-V|--version]
DESCRIPTION
Check file types and compare values.
OPTIONS
- -h, --help
- Print help
- -V, --version
- Print version
EXTRA
Exit with the status determined by EXPRESSION.
An omitted EXPRESSION defaults to false. Otherwise, EXPRESSION is true or false and sets exit status.
It is one of:
- ( EXPRESSION ) EXPRESSION is true - ! EXPRESSION EXPRESSION is false - EXPRESSION1 -a EXPRESSION2 both EXPRESSION1 and EXPRESSION2 are true - EXPRESSION1 -o EXPRESSION2 either EXPRESSION1 or EXPRESSION2 is true
String operations: - -n STRING the length of STRING is nonzero - STRING equivalent to -n STRING - -z STRING the length of STRING is zero - STRING1 = STRING2 the strings are equal - STRING1 != STRING2 the strings are not equal
Integer comparisons: - INTEGER1 -eq INTEGER2 INTEGER1 is equal to INTEGER2 - INTEGER1 -ge INTEGER2 INTEGER1 is greater than or equal to INTEGER2 - INTEGER1 -gt INTEGER2 INTEGER1 is greater than INTEGER2 - INTEGER1 -le INTEGER2 INTEGER1 is less than or equal to INTEGER2 - INTEGER1 -lt INTEGER2 INTEGER1 is less than INTEGER2 - INTEGER1 -ne INTEGER2 INTEGER1 is not equal to INTEGER2
File operations: - FILE1 -ef FILE2 FILE1 and FILE2 have the same device and inode numbers - FILE1 -nt FILE2 FILE1 is newer (modification date) than FILE2 - FILE1 -ot FILE2 FILE1 is older than FILE2
- -b FILE FILE exists and is block special - -c FILE FILE exists and is character special - -d FILE FILE exists and is a directory - -e FILE FILE exists - -f FILE FILE exists and is a regular file - -g FILE FILE exists and is set-group-ID - -G FILE FILE exists and is owned by the effective group ID - -h FILE FILE exists and is a symbolic link (same as -L) - -k FILE FILE exists and has its sticky bit set - -L FILE FILE exists and is a symbolic link (same as -h) - -N FILE FILE exists and has been modified since it was last read - -O FILE FILE exists and is owned by the effective user ID - -p FILE FILE exists and is a named pipe - -r FILE FILE exists and read permission is granted - -s FILE FILE exists and has a size greater than zero - -S FILE FILE exists and is a socket - -t FD file descriptor FD is opened on a terminal - -u FILE FILE exists and its set-user-ID bit is set - -w FILE FILE exists and write permission is granted - -x FILE FILE exists and execute (or search) permission is granted
Except for -h and -L, all FILE-related tests dereference (follow) symbolic links. Beware that parentheses need to be escaped (e.g., by backslashes) for shells. INTEGER may also be -l STRING, which evaluates to the length of STRING.
NOTE: Binary -a and -o are inherently ambiguous. Use test EXPR1 && test EXPR2 or test EXPR1 || test EXPR2 instead. 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 supports.
