awk does not work as a coprocess for me. It hangs when I try to read a result and it probably is buffering the input.
Haven't logged in for a while and I stumbled on this post.
I could never get awk to work as a coprocessor either. I was mentoring a coworker on coprocessors and while he was testing the fundamentals, I noticed that he wrapped awk in a shell script something like this:
...which works well enough for easy text parsing.
Hello everybody,
I have a question about I/O redirection within a coprocess.
I want to setup a coprocess and then redirect output to a file on a remote machine.

I am wracking my brains over this. I am trying to use a Korn Shell script to execute an Oracle PL/SQL procedure, using the Oracle command line interface (sqlplus). The script starts sqlplus in a coprocess, and the two processes communicate using a two-way pipe. The bgnice option is off, so both... (8 Replies)
This is probably a simple one for the wise.
I have just started using a coprocess (first time) in order to facilitate telnet'ing from inside a shell script. It's working, but when I run a remote command I need to get the output into a local variable, but alas my kung-fu is weak.

For example:

While assisting a forum member, I recommended running SQL/Plus in a coprocess (to make database connections and run a test script) for the duration of his script rather than starting/stopping it once for every row in a file he was processing.
I recalled I made a coprocess example for folks at... (2 Replies)

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...

DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
