.TH STEST 1 dmenu\-VERSION |
||||
.SH NAME |
||||
stest \- filter a list of files by properties |
||||
.SH SYNOPSIS |

.B stest |
||||
.RB [ -bcdefghpqrsuwx ] |
||||
.RB [ -C |

.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. |
||||
