and
23,50,01 would be rounded to 23,50,00 (3 Replies)

It seems that perl sprintf uses the round-to-even method:
foreach my $i ( 0.5, 1.5, 2.5, 3.5 ) {
printf "$i -> %.0f\n", $i;
}
__END__
0.5 -> 0
1.5 -> 2
2.5 -> 2
3.5 -> 4
4.5 -> 4
Where we probably wants to use round-half-up, i.e. output should be as below:
0.5 -> 1
1.5 -> 2... (8 Replies)

sg
SG(1) User Commands SG(1) NAME
sg - execute command as different group ID SYNOPSIS
sg [-] [group [-c ] command] DESCRIPTION
The sg command works similar to newgrp but accepts a command. The command will be executed with the /bin/sh shell. With most shells you may run sg from, you need to enclose multi-word commands in quotes. Another difference between newgrp and sg is that some shells treat newgrp specially, replacing themselves with a new instance of a shell that newgrp creates. This doesn't happen with sg, so upon exit from a sg command you are returned to your previous group ID. CONFIGURATION
The following configuration variables in /etc/login.defs change the behavior of this tool: SYSLOG_SG_ENAB (boolean) Enable "syslog" logging of sg activity. FILES
/etc/passwd User account information. /etc/shadow Secure user account information. /etc/group Group account information. /etc/gshadow Secure group account information. SEE ALSO
