I‘m using the date +’%D_%T’ to store Unix system date and time in a shell variable called $_now:
_now=”$(date +’%D_%T’)”
echo $_nowOutputs:
01/20/12_16:10:42
I’d like to replace / and : with _. I’m aware of the following sed command:
sed ‘s/\//_/g
> s/:/_/g’ <<<"$_now"Outputs:
01_20_12_16_14_09
How do I specify two pattern within the same sed command to replace | and : with _ so that I can get output as 01_20_12_16_10_42?

I‘m running the Mediawiki software under Apache web server running on the Unix operating systems. I’m getting the following in my php error log:
PHP Fatal error: Cannot redeclare wfProfileIn() (previously declared in /var/www/html/wiki/includes/profiler/Profiler.php:14) in /var/www/html/wiki/includes/ProfilerStub.php on line 25.
How do I fix this problem under Mediawiki version 1.18.0?
