cut -c6-

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

Here, cut has a better performance than sed, but I got problems when used on utf-8 encoded characters. – PSchwede Nov 16 '17 at 10:13

Just to elaborate on @PSchwede's comment, GNU `cut` treats all characters as bytes even when you use the `-c` option. GNU `cut` does not support multi-byte characters and probably will not support multi-byte characters for the foreseeable future – Harold Fischer Jan 09 '20 at 02:22

sed 's/^.....//'

means

replace ("s", substitute) beginning-of-line then 5 characters (".") with nothing.

There are more compact or flexible ways to write this using sed or cut.

How would you do this for the last character of a string? – blarg Jun 23 '15 at 14:34

@blarg try `sed 's/.$//'` – Rodrigo Aug 25 '15 at 18:50
plus 1 for answering the 'with sed' part of the question and then mentioning that `cut` is better – s g Sep 19 '16 at 06:32

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

BSD sed does not accept the *at most* bound (`{,5}`) , this is GNU specific. An expression that works on both would be `sed 's/^.\{5\}//' file.dat` – Tristan Feb 26 '15 at 12:15
