Try:
Zet=$(wc -l < /home/$USER/Desktop/14tilt.txt)
Ted=$(wc -c < /home/$USER/Desktop/14tilt.txt)

Then you should not need the cut commands either...

How about something like:
while read script1 && read script2 <&3
do
"$script1" &
"$script2" &
wait
done < script1.txt 3<script2.txt


Variable script1 is read from file descriptor 0...

Try also awk '!/no hit/' RS= ORS="\n\n" file

tr does not work that way. It deals with individual characters, not strings. Since you gave it two characters on the input, it's expecting 2 characters on the output, too.

This should work:

The standards say that the type time_t is an integral type. They don't specify whether the type is signed or unsigned. On systems with a signed 64-bit time_t, any time from the big bang to the...

There was a major difference in the behavior of the echo utility (or shell built-in) between 4.2BSD (from the University of California, Berkeley) and UNIX System V (from AT&T Bell Laboratories). In...

for ((i=1; i<=65535; i++)); do
printf "%04X\n" "$i"

Posix:

printf "%04X\n" "$((i+=1))"
done

I have found the solution for bash:
mogrify -resize x120 *.jpg

Mogrify is a part of ImageMagick

perl -pe 's/\s(SNAG|MARC|EA|ER)/\n$1/g' file.in > file.out

-n is closer to what you want, but a lot of that pipe chaining in backticks is pointless since you know the PID. Just watch if /proc/pid still exists, each running process gets a directory inside...

You don't really need the non-portable -r option for that sed task. To avoid -r, simply use the equivalent basic regular expression syntax by backslash-escaping the parentheses.
