[linux] Delete the first five characters on any line of a text file in Linux with sed

I need a one-liner to remove the first five characters on any line of a text file. How can I do that with sed?

sed 's/^.\{,5\}//' file.dat worked like a charm for me

awk '{print substr($0,6)}' file

sed 's/^.\{,5\}//' file.dat

Use cut:

cut -c6-

This prints each line of the input starting at column 6 (the first column is 1).
