Searching for escape characters
Hi all
I have been trying to write a script to look for a set of specific escape characters in a file. On viewing the file via vi it shows this :
^[p^@^E^_^@^@^@^@^@^@^@
Vi also reports at the bottom of the screen [noeol] I understand this means no end of line.
I have tried a vary of grep parameters such as grep ^\^. filename grep --binary-file=binary without any luck.
I hope someone has a genius idea!

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. AUTHOR
