Weird Error (: No such file or directory)
Hi Everyone,

I am trying to make this script to use, to find out the DAHDI channel status. Every thing works fine, I even get proper results, however I have this weird error that comes along.
Can someone please help me. Thanks a lot.
Code:
#!/bin/bash

# Color to set the test to when a channel is down (red or green)
# ---------------------------------------------------------------
TESTCOL="red"
COLOR="green"
data=`cat /proc/dahdi/1`
chandata=`echo "${data}" | sed -e 's/\t//' -e 's/ \+//' | grep ^[1-4]`
card=`echo "${data}" | grep ^Span`


# -----------------------------------------------
IFS=$'\n'
for channel in ${chandata}; do
    curcolor="green"
    chinfo=`echo ${channel} | cut -d' ' -f1-3`
    status=`echo ${channel} | grep -i "red" 2>&1`
    if [ ! -z ${status} ]; then
        curcolor=${TESTCOL}
        COLOR=${TESTCOL}
    fi
    MSG="${MSG}
   Channel:${chinfo} ${curcolor}
"
done
unset IFS

# -----------------------------------------------
# Prepend the administrative message to the report
# add the card information, the channel statuses
"${COLOR} ${card} ${MSG}"

Result is as following....
Code:
[root@PBX~]# ./dahdi.sh
./dahdi.sh: line 31: red Span 1: WCTDM/0 "Wildcard A4B" (MASTER)
   Channel:1 WCTDM/0/0 FXSKS green

   Channel:2 WCTDM/0/1 FXSKS green

   Channel:3 WCTDM/0/2 FXSKS red

   Channel:4 WCTDM/0/3 FXOKS green
: No such file or directory

OPTIONS

	      algorithm, -c zip for the Deflate compression algorithm, -c g3 for the CCITT Group 3 compression algorithm,  -c  g4  for	the  CCITT
	      Group 4 compression algorithm, and -c lzw for Lempel-Ziv & Welch (the default).

       -r     Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approxi-
