使用sed删除Linux中文本文件任意一行的前五个字符

Question

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?

Answer 1

Use cut :

cut -c6-

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

Answer 2

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.

Answer 3

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

Answer 4

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

Answer 5

sed 's/^.\\{,5\\}//' file.dat对我来说就像一个魅力
