shell command to delete range of characters from a

问题:

I have a file which has one single line of 50 characters. I want to delete character 12 to 17 and character 33 to 44 using any shell command. Can anyone please guide me on this.

cut removes sections from each line of files. From man cut:

-c
specifies a range of characters

--complement
complement the set of selected bytes, characters or fields

this can be help to print from first to 11th character, from 18th to 32th and from 45th to the end:

cut -c -11,18-32,45- yourFile

or

cut -c 12-17,33-44 text --complement yourFile
