i find this regex sed -i 's/.*\(:.*\)/\1/g' file.txt for remove before : but i need remove the : too, the result apllying this regex in:

[09/11/2020 15:01:37] Name: Hello!

return:

Hello!

but i need only

Hello!

Instead of using a capture group to copy everything after the :, replace everything up to the : with an empty string.

sed -i 's/^.*://' file.txt

CodePudding user response：

You can use

sed -i 's/.*: *//' file.txt

This will remove all text up to last : including : and all spaces (if any) right after the :.

#!/bin/bash
s='[09/11/2020 15:01:37] Name: Hello!'
sed 's/.*: *//' <<< "$s"
# => Hello!
