One of the regular expressions in there is called safetext and looks like:

I need to be able to check for a pattern with | in them. For example an expression like d*|*t should return true for a string like "dtest|test".

Regex Pattern = new Regex("s*\|*d"); //unable to build because of single backslash

I would like to save the output of the uptime command into a csv file in a Bash script. Since the uptime command has different output formats based on the time since the last reboot I came up with a pretty heavy solution based on case, but there is surely a more elegant way of doing this.

Hi all,
I have an associative array in awk that gets populated like this...
chr_count[$3]++
When I try to print my chr_counts I use this:
for (i in chr_count) {
print i,":",chr_count[i];
}
But not surprisingly, the order of i is not sorted in any way.
Is there an easy way to iterate over…
