What would be the best way to check if a particular line (in variable) has an another line (more than 1 char)?
I understand it could be done with 'grep', 'sad', 'awk', by parameter expansion, but all these seems to me havy, worldy, not elegant and overhead in processing
For so common task I would expect something from shell, maybe, close to:
... I used here a '??' as a, kind of, search operator (as '?' is used for another action.)
But I do not know anything like that. - Maybe I just do not know?
Otherwise,
what would be your best aproach to perform that simple action?

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.
