1. The problem statement, all variables and given/known data:
Write a korn shell script with an alfanumeric string as argument. The script lists the file's names in the current directory that contain the given string as substring and that can be read and written.
2. Relevant commands, code, scripts, algorithms:
I can read the string from standard input and also print on screen the file's names which contain the string, but only if use the name of the file as parameter. I can't search the string among all the regular files in my directory and i have no idea on how to filter files basing on permissions.
3. The attempts at a solution (include all code and scripts):
stringhe.rtf is a text file with some random strings created by me. 4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
Università degli Studi di Trieste, Trieste, Italy, Vidimari, IN108
Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

I have this Korn shell script that runs via a cron entry. It runs in a loop "watching" a specific file system for files with a certain name. The file system that it is watching is an upload file system for an FTP server. When files that are the correct name come in, it takes the extension of the... (1 Reply)

escape
escape(1) Mail Avenger 0.8.3 escape(1)NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`

BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
