Currently the fileutil package contains a find, grep, and cat . Other procs that would be useful to add would include wc, tee, head, tail, and perhaps some awk'ish type functions ala Tclx.
Perhaps even some code like Glenn Jackman's:
proc touch {filename {time ""}} {
if {[string length $time] == 0} {set time [clock seconds]}
file mtime $filename $time
file atime $filename $time
}glennj: This proc has been accepted into tcllib 1.2: http://tcllib.sourceforge.net/doc/fileutil.html
What other file related procs would be useful?
