I want to replace spaces from data which are written in brackets using shell script.
my input line is

2012-05-21 06:37:16 M NumberOfHwEntitiesMismatch Cabinet=1
(SAU that is not configured detected.)

I want my output to be:

2012-05-21 06:37:16 M NumberOfHwEntitiesMismatch Cabinet=1
(SAU_that_is_not_configured_detected.)

Please suggest me something….

    Using awk, split on “(” and then use gsub to replace space with underscore in the second field.

    Example:

    $ awk -F\( '{gsub(" ","_", $2);print $1"("$2}' <<< "2012-05-21 06:37:16 M NumberOfHwEntitiesMismatch Cabinet=1 (SAU that is not configured detected.)"
2012-05-21 06:37:16 M NumberOfHwEntitiesMismatch Cabinet=1 (SAU_that_is_not_configured_detected.)

    (This assumes that your input has only one set of brackets.)
