Bash script to read a file from particular line till required line and process
Hi All,
Am trying to write wrapper shell/bash script on a utility tool for which i need to pass 2 files as arugment to execute utility tool.
Wraper script am trying is to do with above metion 2 files.
utility tool accepts :
a. userinfo file : which contains username
b. item file : which contains items to be processed by mentioned users from userinfo file.
Below script works fine for userfile and itemfile
Am thinking of writing a wrapper script which call this script but in the wapper script it should execute utility tool from specified lines to perticular line from userfile and even for itemfile.
for ex : say userfile has 100 users and itemfile has 1000 items. so, i should call the wrapper script with passing argument saying run script for users from line 20-45 from userfile and say item from line 250-400 from itemfile.
basically it should run the utility tool from specified user number to a specfied item numbers.
Any help will be much appreciated.
Thanks

LEARN ABOUT PHP
is_uploaded_file
IS_UPLOADED_FILE(3) 1 IS_UPLOADED_FILE(3)is_uploaded_file - Tells whether the file was uploaded via HTTP POSTSYNOPSIS
bool is_uploaded_file (string $filename)
DESCRIPTION
Returns TRUE if the file named by $filename was uploaded via HTTP POST. This is useful to help ensure that a malicious user hasn't tried
to trick the script into working on files upon which it should not be working--for instance, /etc/passwd.
This sort of check is especially important if there is any chance that anything done with uploaded files could reveal their contents to
the user, or even to other users on the same system.
For proper working, the function is_uploaded_file(3) needs an argument like $_FILES['userfile']['tmp_name'], - the name of the uploaded
file on the client's machine $_FILES['userfile']['name'] does not work.
PARAMETERS
o $filename
- The filename being checked.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
is_uploaded_file(3) example
<?php
if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
echo "File ". $_FILES['userfile']['name'] ." uploaded successfully.
";
echo "Displaying contents
";
readfile($_FILES['userfile']['tmp_name']);
} else {
echo "Possible file upload attack: ";
echo "filename '". $_FILES['userfile']['tmp_name'] . "'.";
}
?>
