Let's say you have these three files:
"file 1" "file 2" "file 3"
"lam file1 file2 file3
" will produce:
"file 1file 2file 3"
Note that there is a fairly wide-spread program by the same name that does more or less the same thing. I wrote this because the other version wasn't available one day when I needed it, and besides its argument syntax is weird.
