Note that the 'server.log' in that grep command is almost certainly incorrect. The dot is behaving as a wildcard when what's most likely intended is a literal dot.
True. The other plausible explanation is that the writer of this intended to search a file named "server.log" for a string/regexp he just forgot to write. This would mean the statement is equally incorrect, but so for a different reason.
In any way, your solution is preferable to this, albeit in case the intended purpose was like i said it would have to be modified slightly:
Specifically what is the purpose of sed?
What is f?
Why is the 'cp f $phonefile' line needed when the script ‘goes live'?
Why might that two commands following sed be commented out at the present time ( i.e., during development)?

Hi,
I saw this. But I don't know why we need this?
ls mydir > foo.txt ## I know what this will do, it will take the results and write to the file called foo.txt
ls mydir > foo.txt 2>&1 ## Don't know why we need 2>&1
Thanks. (2 Replies)

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.
