The Remote Searcher utility

The rsch(Remote Searcher) app is an utility that allow you to make remote searches according given one or more keyword pattern.

How it works

You can run the rsch command following way:

rsch -s 192.168.0.1 -u foo -p 123 "keyword" /directory-dst/

where:

-s parameter is the IP/Hostname from server where the search will be done.
-u parameter is the user to the remote server.
-p parameter is the password to the remote server.

and:

keyword argument is the keyword match to the given pattern.
/directory-dst/(or filename) argument is the directory or filename destination that contains the keyword.

You else can use the the long parameter option instead short parameter option if you so wish:

rsch --server 192.168.0.1 --user foo --password 123 "keyword" /directory-dst/

Follows more examples:

Suppose that you desire search by the keyword dio stored in file passwd found on /etc/ directory on server called myserver.com, you could do it:

rsch -s myserver.com -u root -p 123pass "dio" /etc/password

So, the output it will look like this:

So, how you can see output above, it has been matched two lines with the keyword "dio". The first line has been matched the word "PulseAudio". The second line has been matched the words "dio" and "Dio".

The rsch utility wrapper the grep utility, so, you can use the same options that you use in the grep command. Let's suppose that you want just matcher the word "dio". In this case, you could use the parameter -w or --word-regexp, available in grep command, which ensures us select only those lines containing matches that form whole words. To use the option -w or any another available in grep command, just only add the -g or --grep option in rsch command followed with desired option. E.g:

rsch -s myserver.com -u root -p 123pass --grep=w "dio" /etc/passwd

So, the output will look just the line containing the matches that form whole words:

An another option available in grep command is the -i or --ignore-case, which ignores case distinctions in both the pattern and the input files. E.g:

rsch -s myserver.com -u root -p 123pass --grep=wi "dio" /etc/passwd

Will match both, lowercase and/or uppercase whole word dio or Dio. Therefore, without the option -i or --ignore-case, only the word dio would be match.

The rsch utility provides their own system of highlighting color, that surrounds the keyword and their corresponding line matched. If you want use it, just only add the option -c or --color. E:g

rsch -s myserver.com -u root -p 123pass --color "dio" /etc/passwd

The output:

As explain previously, if you add the -i parameter from grep utility using the benefit of the own color highlighting offered by rsch utility, all keyword case distinctions will be ignored. Look the same example above with --grep=i option:

rsch -s myserver.com -u root -p 123pass --color --grep=i "dio" /etc/passwd

Now, the output matches and surrounds(dio, Dio, DIO and so on) keywords:
