If you are using bash, there is no need to call any external tools to perform this. You can use parameter expansion alone as per below:
Code:
# Example line variable
line="this is an example line of text"
# Now lets delete 8 characters after the 10th character (deleting the word example)
echo ${line/${line:10:8}}

wordwrap
WORDWRAP(3) 1 WORDWRAP(3)wordwrap - Wraps a string to a given number of charactersSYNOPSIS
string wordwrap (string $str, [int $width = 75], [string $break = "0], [bool $cut = false])
DESCRIPTION
Wraps a string to a given number of characters using a string break character.
PARAMETERS
o $str
- The input string.
o $width
- The number of characters at which the string will be wrapped.
o $break
- The line is broken using the optional $break parameter.
o $cut
- If the $cut is set to TRUE, the string is always wrapped at or before the specified $width. So if you have a word that is larger
than the given width, it is broken apart. (See second example). When FALSE the function does not split the word even if the $width
is smaller than the word width.
RETURN VALUES
Returns the given string wrapped at the specified length.
