Retrieve the time into an AWK variable
Hello,
does anyone know how to retrieve the current time, and more generally any result from an external command inside an AWK script to assign it to a variable?
If so, please enlighten me.

ModeratorRead man awk
Search "Time Functions" "systime"
example:
johand@horus:~$ awk '{ print strftime("%Y/%m/%d-%H:%M:%S",systime()) } '

Regarding external commands, I did not go into depth, but there is a system command (you can retrieve the exit code of the command).
I did not see a trace of popen. But this may vary with awk versions...

ModeratorThank you for your reply, but my awk (AIX 5.2, I didn’t specify that) doesn’t know systime or strftime...
And for the system command, we indeed only get the return code back (you know I had tested it)...
I was thinking more of a trick with indirection, like toto=`system(date)` or toto=$(system(date))
as in shell... but it didn’t work :-(
