It would help if you give the structure of the text file's contents.

alias filterext {
if ($isfile($2-)) {
var %re = $+(/^\Q,$replacexcs($1,;,\E|\Q,\E,\E\\E\Q),\E$/)
filter -ffg $qt($2-) nul %re
echo -a * Found: $filtered
}
}/filterext <extensions> <file> <extensions> should be a list of extensions you want to match like *.mp3;*.mpg;*.etc

alias ext {
var %x = 1, %f = $$1
while (%x <= $lines%f)) {
if ($gettok($read(%f,%x),2,46)) inc $+(%,$v1)
inc %x
}
}
/ext <file>

There's a few problems with this script. 1) Setting %f to $$1 will not take into account files that have spaces in the name. Use $$1- instead. 2) $lines%f should be $lines(%f) 3) Calling $read without the 'n' flag will evaluate identifiers in the file. Also, that loop could be greatly sped up by setting $lines(%f) to a variable instead of calling it in each iteration of the loop: var %x = 1, %f = $$1-, %l = $lines(%f)
while (%x <= %l) {
...
}

alias ext {
var %n = ext
.fopen %n $$1-
if ($ferr) { .fclose %n | return }
if ($fopen(%n)) {
while (!$feof) {
if ($gettok($fread(%n),2,46)) { inc $+(%,$v1) }
}
.fclose %n
}
}
I think this might be a little faster than my $read post.

Nope, type:
/ext <file>
Then it'd look like:
%png 1
%jpg 2
%bmp 30
Or something similar

Silly mistake.. just remove the "^" character from my alias: alias filterext {
if ($isfile($2-)) {
var %re = $+(/\Q,$replacexcs($1,;,\E|\Q,\E,\E\\E\Q),\E$/)
filter -ffg $qt($2-) nul %re
echo -a * Found: $filtered
}
}
