if grep -qiw "$name | $number" teledir.txt; then
Code:
if grep -qiw "$name\|$number" teledir.txt; then

and with this design, 2 parameters are needed and not equal to an empty string
Otherwise
Code:
if [ $# -eq 1 ]; then
    if grep -qiw "$name" teledir.txt; then
        echo exists
    else
        echo no exists
    fi

Code:
#!/bin/bash
if [ $# -lt 2 ]; then
        echo 2 parameters required
        exit
else
        if [ -z "$1" -o -z "$2" ]; then
                echo The parameter cannot be an empty string
                exit
        fi

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
