Signal name for signal number

[feherke]

Hi

I need to find out the signal name for a signal number. For example, for the number 15, to get the string SIGTERM.

I use [tt]Bash[/tt], and I'm interested in solutions other then using an array. ( Handmade, or generated from [tt]kill -l[/tt] or [tt]trap -l[/tt] output. )

A starting point:
signum=15
kill -l | sed -n "${signum}p"

Hope This Helps, PH.

Hi

Good idea in on point : the list of the [tt]kill[/tt] built-in of [tt]Bash[/tt] is different then the one of [tt]/bin/kill[/tt].

Sadly, the built-in's list is on multiple columns affected by [tt]$COLUMNS[/tt] and the standalone's list is not ordered. But anyway, both has gaps.

In bash:
signum=15
kill -l | awk '{for(i=1;i<NF;++i)if($i=="'$signum')")print $(i+1)}'

Hope This Helps, PH.

Hi

Thanks. Probably I will use something like this next time. Excepting when needed in a loop. In which case the solution is stil the array.
