File existence
Hi

I'm using the below command in shell script to check for file exists in the path

if [ ! -r $path/$test.csv ]
.....
fi

path and test are variables

path and the file exists but the commands inside if condition is executed (! operator used)

Is the above way of checking for file existence is correct?

Thanks

shtool-mkln

SHTOOL-MKLN.TMP(1)					      GNU Portable Shell Tool						SHTOOL-MKLN.TMP(1)

NAME

       shtool-mkln - GNU shtool enhanced ln(1) replacement

SYNOPSIS

       shtool mkln [-t|--trace] [-f|--force] [-s|--symbolic] src-path [src-path ...]  dst-path

DESCRIPTION

       This is a ln(1) style command. It is enhanced to provide automatic calculation and usage of relative links with the shortest possible path,
       if possible. Usually if src-path and dst-path are not absolute paths or at least they share a common prefix except the root directory
       (``"/"''). When more than one src-path is specified, all of them are linked into dst-path.

OPTIONS

       The following command line options are available.

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

       -f, --force
	   Force the creation of the link even if it exists. Default is to fail with error.

       -s, --symbolic
	   Create a symbolic link instead of a hard-link.

EXAMPLE

	#   shell script
	shtool mkln -s foo/bar baz/quux

HISTORY

       The GNU shtool fixperm command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for ePerl.

SEE ALSO

       shtool(1), ln(1).
