Won't necessarily work if the result is not a simple command, though…


tg_AT_blau:~ $ cat >x1
printf 'echo "Hello\tWorld!" | hexdump -C\n'
tg_AT_blau:~ $ cat >x2
eval exec "$(./x1)"
tg_AT_blau:~ $ chmod +x x?
tg_AT_blau:~ $ ./x2
00000000 48 65 6c 6c 6f 09 57 6f 72 6c 64 21 0a |Hello.World!.|

[...] if maybe ext3fs wasn't a better pick, or jfs, or maybe reiserfs, oh but
what about xfs, and if only i had waited until reiser4 was ready... in the be-
ginning, there was ffs, and in the middle, there was ffs, and at the end, there
