DESCRIPTION

24       The module is used to replace common UNIX commands.  In all cases the
25       functions work from @ARGV rather than taking arguments.  This makes
26       them easier to deal with in Makefiles.  Call them like this:
27
28         perl -MExtUtils::Command -e some_command some files to work on
29
30       and NOT like this:
31
32         perl -MExtUtils::Command -e 'some_command qw(some files to work on)'
33
34       For that use Shell::Command.
35
36       Filenames with * and ? will be glob expanded.
37
38   FUNCTIONS
39       cat
40               cat file ...
41
42           Concatenates all files mentioned on command line to STDOUT.
43
44       eqtime
45               eqtime source destination
46
47           Sets modified time of destination to that of source.
48
49       rm_rf
50               rm_rf files or directories ...
51
52           Removes files and directories - recursively (even if readonly)
53
54       rm_f
55               rm_f file ...
56
57           Removes files (even if readonly)
58
59       touch
60               touch file ...
61
62           Makes files exist, with current timestamp
63
64       mv
65               mv source_file destination_file
66               mv source_file source_file destination_dir
67
68           Moves source to destination.  Multiple sources are allowed if
69           destination is an existing directory.
70
71           Returns true if all moves succeeded, false otherwise.
72
73       cp
74               cp source_file destination_file
75               cp source_file source_file destination_dir
76
77           Copies sources to the destination.  Multiple sources are allowed if
78           destination is an existing directory.
79
80           Returns true if all copies succeeded, false otherwise.
81
82       chmod
83               chmod mode files ...
84
85           Sets UNIX like permissions 'mode' on all the files.  e.g. 0666
86
87       mkpath
88               mkpath directory ...
89
90           Creates directories, including any parent directories.
91
92       test_f
93               test_f file
94
95           Tests if a file exists.  Exits with 0 if it does, 1 if it does not
96           (ie.  shell's idea of true and false).
97
98       test_d
99               test_d directory
100
101           Tests if a directory exists.  Exits with 0 if it does, 1 if it does
102           not (ie. shell's idea of true and false).
103
104       dos2unix
105               dos2unix files or dirs ...
106
107           Converts DOS and OS/2 linefeeds to Unix style recursively.
