Replace a string @CURRANGE("***","***") to @CURRANGE("xxx","xxx") in a file

Hi all,

I have a file in which I need to find and replace a string @CURRANGE("***","???") to @CURRANGE("---","^^^") where ***, ???, --- and ^^^ can be any string. I feel I need to use sed to do it but if someone could be more specific that would be much more helpful.

Thank You.
Mayur.

Hi Mayur and welcome to LinuxQuestions!

Here is an example:

Code:

sed 's/@CURRANGE("[^"]*","[^"]*")/@CURRANGE("new_string_one","new_string_two")/g' file

where the expression [^"]* means zero or any number of characters different than ". This ensures that two or more expressions in the same line (if any) are changed accordingly. Example:

Code:

$ cat file

text @CURRANGE("any string","yet another string") text @CURRANGE("whatever","235472934629746") text

$

$ sed 's/@CURRANGE("[^"]*","[^"]*")/@CURRANGE("new_string_one","new_string_two")/g' file

text @CURRANGE("new_string_one","new_string_two") text @CURRANGE("new_string_one","new_string_two") text

Use the -i option of sed if you want to edit the file in place. Use -i.bck to keep a backup copy of the original file, that will be named by adding the (custom) suffix .bck. Hope this helps.
