Full Discussion: [sh] While loop -> Expression recursion level exceeded
Top Forums Shell Programming and Scripting [sh] While loop -> Expression recursion level exceeded Post 302305987 by machinogodzilla on Friday 10th of April 2009 11:00:24 AM
Old 04-10-2009
Here is my solution based on my very limited knowledge. It prints "error" for every key in file2 that doesn't appear in file1.

Code:
#!/bin/bash

awk -F= '{print $1}' < file1 > keys

while read LINE

do
        TMP=`echo $LINE | sed s/=.*//`
        awk -F= -v v=$TMP '{if (v==$1) i=1}END{if (i!=1) print "error"}' < keys
done < file2

smd-loop

smd-loop(1)						 Sync Mail Dir (smd) documentation					       smd-loop(1)

NAME

       smd-loop - iterates smd-pull and smd-push

SYNOPSIS

       smd-loop [-vt]

DESCRIPTION

       smd-loop  runs  smd-push and smd-pull at regular intervals as defined by the user in the ~/.smd/loop configuration file. On errors that are
       reported to be transient, it retries a second time before failing.

       The configuration file is line-oriented. Each line is composed of three space separated fields:	pull-frequency,  push-frequency  and  end-
       point-name. Frequencies are expressed in minutes, while endpoint name is a valid name for smd-pull(1) and smd-push(1). Lines beginning with
       # are considered as comments. The following example calls the command smd-pull default every 3 minutes,	and  smd-push  default	every  10.
       Example:

	   # pull-frequency push-frequency endpoint-name
	     3		    10		   default

OPTIONS

       -v     Increase program verbosity (printed on stderr)

       -t     Just create a template configuration file if none

FILES

       ~/.smd/loop

SEE ALSO

       mddiff(1), smd-server(1), smd-client(1), smd-push(1), smd-pull(1)
