shell - How to store the output of a Bash command inside >() in a variable? -


i have this:

tee < /some/big/file >(wc -c) >(md5sum) | ...

instead of writing results of wc -c , md5sum stdout, want store results 2 variables later processing. don't want read file more once. how can accomplish that?

you can fifo , temporary files.

input=/some/big/file mkfifo tmp wc -l <tmp >wc.out & md5=$(tee <"$input" tmp | md5sum) fg lines=$(cat wc.out) rm tmp rm wc.out

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
