To remove the first line from the file in "$file" then you could use:
tail $file -n`echo \`grep -c '' $file\`-1|bc`

I told you already that this cannot be done! (In this, merged, thread).

Also: Did you try the solution I offered at the end of the thread?????

PS: Do _not_ repeat the same question in different forms. This is the third fourth time you ask the same question.

sed -i 1d file
