Finding/replacing text and redirection help
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!
1. The problem statement, all variables and given/known data:
What command would rename "sequentialInsert", in
~cs252/Assignments/commandsAsst/project/arrayops.h, to
"orderedInsertion" in ~/UnixCourse/commandsAsst/arrayops.h?
2. Relevant commands, code, scripts, algorithms:
I think I need to use the grep, find, and redirection operators, but I am not sure
3. The attempts at a solution (include all code and scripts):
grep 'sequentialInsert' ~cs252/Assignments/commandsAsst/project/arrayops.h > 'orderedInsertion' ~.UnixCourse/commandsAsst/arrayops.h

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.
