NAME test,[test odto vlainuiiy SYNOPSIS test xrsin[testepeso DESCRIPTION Tetest tlt vlae h xrsinad fi vlae otu, returns a zero (true) exit status; otherwise it returns 1 (false). If there is no expression, test also returns 1 (false). Aloeaosadfasaesprt ruet otetest tlt. The following primaries are used to construct expression: bb file True if file exists and is a block special file. cc file True if file exists and is a character special file. dd file True if file exists and is a directory. ee file True if file exists (regardless of type). ff file True if file exists and is a regular file. gg file True if file exists and its set group ID flag is set. hh file True if file exists and is a symbolic link. This operator is retained for compatibility with previous versions of this program. Do not rely on its existence; use LL instead. kk file True if file exists and its sticky bit is set. nn string True if the length of string is nonzero. pp file True if file is a named pipe (FIFO). rr file True if file exists and is readable. ss file True if file exists and has a size greater than zero. tt filedescriptor True if the file whose file descriptor number is filedescriptor is open and is associated with a terminal. uu file True if file exists and its set user ID flag is set. ww file True if file exists and is writable. True indicates only that the write flag is on. The file is not writable on a read-only file system even if this test indicates true. xx file True if file exists and is executable. True indicates only that the execute flag is on. If file is a directory, true indicates that file can be searched. zz string True if the length of string is zero. LL file True if file exists and is a symbolic link. OO file True if file exists and its owner matches the effective user id of this process. GG file True if file exists and its group matches the effective group id of this process. SS file True if file exists and is a socket. file1 nntt file2 True if file1 exists and is newer than file2. file1 oott file2 True if file1 exists and is older than file2. file1 eeff file2 True if file1 and file2 exist and refer to the same file. string True if string is not the null string. s1 == s2 True if the strings s1 and s2 are identical. s1 !!== s2 True if the strings s1 and s2 are not identical. s1 << s2 True if string s1 comes before s2 based on the ASCII value of their characters. s1 >> s2 True if string s1 comes after s2 based on the ASCII value of their characters. s1 True if s1 is not the null string. n1 eeqq n2 True if the integers n1 and n2 are algebraically equal. n1 nnee n2 True if the integers n1 and n2 are not algebraically equal. n1 ggtt n2 True if the integer n1 is algebraically greater than the integer n2. n1 ggee n2 True if the integer n1 is algebraically greater than or equal to the integer n2. n1 lltt n2 True if the integer n1 is algebraically less than the inte- ger n2. n1 llee n2 True if the integer n1 is algebraically less than or equal to the integer n2. These primaries can be combined with the following operators: !! expression True if expression is false. expression1 aa expression2 True if both expression1 and expression2 are true. expression1 oo expression2 True if either expression1 or expression2 are true. ((expression)) True if expression is true. The aa operator has higher precedence than the oo operator.
