Hi Friends,
I don't understand why "a" is always being printed as zero, when I execute the following command.
awk '{if($6||$8||$10||$12==0)a=b=c=d=0;else (a=$5/$6);(b=$7/$8);(c=$9/$10);(d=$11/$12); {print... (6 Replies)
Hello,
How can I add a logic to awk to tell it to print 0 when encountering a division by zero attempted? Below is the code. Everything in the code works fine except the piece that I want to calculate read/write IO size. I take the kbr / rs and kbw / ws. There are times when the iostat data... (5 Replies)

make_socksfc
MAKE_SOCKSFC(8) System Manager's Manual MAKE_SOCKSFC(8)NAME
make_socksfc - Generates frozen configuratyion file for SOCKS clients
SYNOPSIS
make_socksfc [infile [outfile] ]
DESCRIPTION
make_socksfc reads in a plain-text configuration file for the SOCKS clients and produces a frozen configuration file as the output.
Both arguments are optional. The default for infile is /etc/socks.conf; the default for outfile is /etc/socks.fc. You may specify infile
while omitting outfile, but you cannot specify outfile without also speficying infile.
The contents of the frozen configuration file is essentially the memory image of the parsed input file. Using the frozen configuration file
can reduce the start-up delay of the SOCKS client programs since they no longer have to parse the file contents.
When the SOCKS client starts, it always looks for the frozen configuration file /etc/socks.fc first . If that file is not found, it then
tries to use the plain-text configuration file /etc/socks.conf. If you use frozen configuration, you must remember to run make_socksfc
every time after you modify the plain-text file or the SOCKS clients will continue to use the frozen file of a previous configuration.
To find out the contents of a frozen configuration file, use dump_socksfc.
