end of file

[Yarka]

i've script as:

cat $1 | while read LINE; do
until [ "$a" -eq 1 ]; do
...
read LINE
...
done

read LINE

until [ "$b" -eq 1 ]; do
...
read LINE
...
read LINE
...
done
done

how i can indicate end of file in the conditions of until?


thanks.

Something along the lines of

until ! read line
do
  until [ $a -eq 1 ]
  do
    ...
  done
  until [ $b -eq 1 ]
  do
    ...
  done
done < $1

Hmm

I think I see what you mean this time
In pseudo code

while more file to read
do
  ...
  until $a equals 1 OR end of file
  do
    ...
  done
  until $b equals 1 OR end of file
  do
    ...
  done
  ...
done

How about

while read line
do
  ...
  while read line
  do
    ...
    ...
    [[ $a -eq 1 ]] && break
  done
  while read line
  do
    ...
    ...
    [[ $b -eq 1 ]] && break
  done
  ...
done

There will still be some issues at the boundaries which you will have to watch closely but
