I'm trying to grep content from one file in another file.
The file that I'm searching into is large and hence I need to temporarily unzip it first.
The command above worked and I get lines matching my grep content but I have a huge list to look into so I tried command below but it did not give any matching result . The text file contains exactly what I used above to write manually, so in theory the command below should produce the same result as command above. So I'm not sure why it doesn't produce matching lines and how could I modify the command?
This is how HIGH_conf_chrom2.txt look like

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.
