Facing problem in incrementing the variable
When I did,
echo $SHELL in cmd prompt of putty,
its displaying /bin/sh
And in my shell script.,
I hav started with.,
#!/bin/sh
and
i=1;
while [ $i -lt $VAR ] ;
do
.
.
.
i=$[$i + 1];
#i=`expr $i +1`;
#i=`bc $i + 1`
#i=`($i+1 | bc)`
done
I am trying to increment the var, its running to infinite loop with o/p:
inside loop
./run1.sh: +: not found
inside loop
./run1.sh: +: not found
inside loop
./run1.sh: +: not found
inside loop
./run1.sh: +: not found
inside loop
./run1.sh: +: not found
inside loop
./run1.sh: +: not found
.
.
.
.
Also I tried with other ways of incrementing the var, as indicated with bold text.
I request you to guide to debug this error.
Thanks.,

shells
shells(4) File Formats shells(4)
NAME
shells - shell database
SYNOPSIS
/etc/shells
DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.
A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines
which search the file. Blank lines are also ignored.
The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
/bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
/usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.
Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
