Using variables in gnuplot within a shell script
Hi everybody, please help me with this problem
Suppose I have a script like this to run commands of gnuplot.
Code:
#!/bin/sh
lib=$1
old="output/old/$lib.dat"
new="output/new/$lib.dat"

gnuplot << EOF
set logscale x
set logscale y
set size square
set grid
set pointsize 1
plot "< paste $old $new" using 1:4 ti '$lib'
EOF

Since I use logscale, some of my data which have value zero can not be displayed. So I want to write a simple function f(x) that, if the value is 0.000, I will change it to 0.001. Then I use the function on "using f($1):f($4)".
But I am afraid that the variable showing column $1 and $4 will be confused with the 1st and 4th variables of the shell script. Please tell me how I can deal with this problem.

Thank you very much.

digest(1)							   User Commands							 digest(1)

NAME

       digest - calculate a message digest

SYNOPSIS

       /usr/bin/digest -l | [-v] -a algorithm [file...]

DESCRIPTION

       The  digest  utility  calculates  the  message digest of the given file(s) or stdin using the algorithm specified. If more than one file is
       given, each line of output is the digest of a single file.

OPTIONS

       The following options are supported:

       -a algorithm    Specifies the name of the algorithm to use during the encryption or decryption process. See USAGE, Algorithms, for details.

       -l	       Displays list of algorithms available on the system. This list can change depending on the  configuration  of  the  crypto-
		       graphic framework.

       -v	       Verbose output. Includes the algorithm name and filename in the output.

USAGE

   Algorithms
       These algorithms are provided by the Cryptographic Framework. Each algorithm supported by the command is an alias of the PKCS #11 mechanism
       for easier access. For example, sha1 is an alias to CKM_SHA_1.

       These aliases are used with the -a option and are case-sensitive.

EXAMPLES

       Example 1: Simulating output of the common md5sum program

       example$ digest -v -a md5 /usr/bin/vi
       md5 (/usr/bin/vi) = e4e3588c5212903847c66d36b1a828a5

       Example 2: Digesting a file

       To generate the sha1 digest of the file /etc/motd:

       example$ digest -a sha1 /etc/motd
       9498a4f5303d056ad3ecae826b59f41448d63790

       Example 3: Generating a directory manifest with sha1
