If condition getting bypassed
Hi,
I am trying something like:

c=`awk -F"|" '{ print NF }' test.txt`
echo "c is $c"
if [ c > 2 ]
then
echo "More than One field"
else
echo "One field"
fi

The test.txt file has something like:
lkadaldj|
fdsakfdsafd|
ddddddd|

The value of "c" is 2 in above case. If any rows in the file has more than 2 columns(something like: lkadaldj999|2345| ) then it should get inside "if" condition.

But the above code is bypassing the "if condition for all the rows" and getting inside the "if" statement even if the value of "c" is 2 for all the rows. I am getting "More Than One Field" as an answer even if all the rows are having two columns. I am using ksh.

I also tried something like:
if test $c -gt 2 ---> I get error :test: 2: unknown operand"

I will really appreciate any help in correcting this code.

Thanks
Raj

echo(3XCURSES)						  X/Open Curses Library Functions					    echo(3XCURSES)

NAME

       echo, noecho - enable/disable terminal echo

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include  -L	/usr/xpg4/lib 
	-R  /usr/xpg4/lib  -lcurses  [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

       int echo(void);

       int noecho(void);

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
       curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control  soft-
       ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined.

       Upon successful completion, these functions return OK. Otherwise, they return ERR.

ERRORS

       No errors are defined.
