So, in awk, I've always put my variable assignments inside of the curly braces, just like dad, and grandpa, and the 26 generations before them. But today I came upon an awk statement that had them outside the braces-- blasphemy!
Seriously, though, is there any practical difference? I was... (3 Replies)
Hi,
Was hoping someone could help with the following:
while read line; do pntadm -P $line | awk '{if (( $2 == 00 && $1 != 00 ) || ( $2 == 04 )) print $3,$5}'; done < /tmp/subnet_list
Anyone know if it is possible to assign $3 and $5 to separate variables within the {} brackets?
Thanks... (14 Replies)

env
ENV(3) Library Functions Manual ENV(3)NAME
env - environment variables
SYNOPSIS
bind #e /env
/env/var1
/env/var2
...
DESCRIPTION
The env device serves a one-level directory containing files with arbitrary names and contents. The intention is that the file name is the
name of an environment variable (see rc(1)), and the content is the variable's current value.
When a fork(2) system call creates a new process, both the parent and the child continue to see exactly the same files in the env device:
changes made in either process can be noticed by the other. In contrast, an rfork system call with the RFENVG bit set (see fork(2)) causes
a split: initially both process groups see the same environment files, but any changes made in one process group cannot be noticed by the
other. An rfork with RFCENVG splits and then clears the environment.
SEE ALSO rc(1), fork(2)SOURCE
/sys/src/9/port/devenv.c
BUGS
A write starting at an offset after the current extent of a file yields an error instead of zero filling.
