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

Code:

mv myfile.txt myfile.tmp
sed 1d myfile.tmp > myfile.txt
rm myfile.tmp

Hi,

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.

There is no need for script here . just do it using sed,

Code:

sed -i 1d file
