Problem in ksh script ( String comparison )
hi ,
i am trying to compre two strings
if [[ $var1 = $var2 ]] or if [[ "$var1" = "$var2" ]]
when the length of var1 is small (around 300-400 char ) it works fine
but when it is large (around 900-1000 chars) it fails
is there any limitations for this type of comparison ???

ENV(3) Library Functions Manual ENV(3)
NAME
env - environment variables
SYNOPSIS
bind #e /env
/env/var1
/env/var2
...
DESCRIPTION
The env device serves a one-level directory containing files with arbitrary names and contents. The intention is that the file name is the
name of an environment variable (see rc(1)), and the content is the variable's current value.
When a fork(2) system call creates a new process, both the parent and the child continue to see exactly the same files in the env device:
changes made in either process can be noticed by the other. In contrast, an rfork system call with the RFENVG bit set (see fork(2)) causes
a split: initially both process groups see the same environment files, but any changes made in one process group cannot be noticed by the
other. An rfork with RFCENVG splits and then clears the environment.
SEE ALSO
rc(1), fork(2)
SOURCE
/sys/src/9/port/devenv.c
BUGS
A write starting at an offset after the current extent of a file yields an error instead of zero filling.
