It was quite a real command! It was something like:
sort -u +2 list |while read v1 v2 v3; do {
echo "$v1 has problems with $v2..." |fmt; grep -w $v2 list; } |
echo /path/to/my/script --opt1=$v1 --opt2="$v2...$v3"; done
My /path/to/my/script script uses both command line options and stdin.
Because the script performs some action (i.e. it is "destructive"),
I used "echo" as a comment to find out and check twice the commands that
were going to be executed. No matter what -- it said that the script
was going to be executed only once! After some mangling I realized that
this was rather zsh problem.
Of course my reduced version with `seq' looks like a nonsense code. :)
