Top Forums Shell Programming and Scripting Replacing text between two square brackets Post 302476786 by zaff on Thursday 2nd of December 2010 03:01:13 PM

basically all i need is the following:

1. command similar to one u provided, but assigning the string in the brackets to a variable. i will then use this variable to generate an md5 (this i can do).

2. replace the content of the brackets with the md5. This command u have already kindly provided:

Code:
echo "0001  zz 43242 [replace this text] name" |sed '/^0001/s/\[.*\]/my_md5/'

........only thing is, i need the brackets to remain as they are and not be removed along with the original string.

Regards,
Zaff
