.RB [ -C
.IR dir ]
.RB [ -n
.IR file ]
.RB [ -o
.IR file ]
.RI [ file ...]
.SH DESCRIPTION
.B stest
takes a list of files and filters by the files' properties, analogous to
.IR test (1).
Files which pass all tests are printed to stdout. If no files are given as
arguments, stest will read a list of files from stdin, one path per line.
.SH OPTIONS
.TP
.BI \-C " dir"
Tests files relative to directory
.IR dir .
.TP
.B \-b
Test that files are block specials.
.TP
.B \-c
Test that files are character specials.
.TP
.B \-d
Test that files are directories.
.TP
.B \-e
Test that files exist.
.TP
.B \-f
Test that files are regular files.
.TP
.B \-g
Test that files have their set-group-ID flag set.
.TP
.B \-h
Test that files are symbolic links.
.TP
.BI \-n " file"
Test that files are newer than
.IR file .
.TP
.BI \-o " file"
Test that files are older than
.IR file .
.TP
.B \-p
Test that files are named pipes.
.TP
.B \-q
No files are printed, only the exit status is returned.
.TP
.B \-r
Test that files are readable.
.TP
.B \-s
Test that files are not empty.
.TP
.B \-u
Test that files have their set-user-ID flag set.
.TP
.B \-w
Test that files are writable.
.TP
.B \-x
Test that files are executable.
.SH EXIT STATUS
.TP
.B 0
At least one file passed all tests.
.TP
.B 1
No files passed all tests.
.TP
.B 2
An error occurred.
.SH SEE ALSO
