Top Forums Shell Programming and Scripting sed command to replace one value which occurs multiple times Post 302995769 by Don Cragun on Wednesday 12th of April 2017 03:02:08 AM

You could change it to:
Code:
	sed -i	's/\('$x'.*\)'$value'/\1'$tmp'/' file

and it will work with your sample data, but
Code:
	sed -i	"s/\($x.*\)$value/\1$tmp/" file

is MUCH easier to read and will still work if either or both of your search pattern and replacement string contain spaces and/or tabs.
