I'm trying to run a perl script found at http://wiki.scribus.net/index.php/Web_optimised_PDF.
running "compress-newsletter.pl input.pdf" produces the result:
-bash: compress-newsletter.pl: command not found
Was wondering if any perl guru's could help me with a quick log file adjustment. I have a text file that looks like so (tabs and newlines are revealed so you can see what separates the data):
There are maybe 100 lines of text in this file at any given time. I need to delete all duplicate lines only looking at the first bit of text prior to the first tab. It doesn't matter which one gets deleted as long as there are no two lines that begin with that same text at the beginning before the first tab. So in this example, either the fist line "1234" or the last line "1234" would need to be deleted. I already have code in my script that opens the files - I just need the code to read the text into an array and the part that would find matches based on the above criteria, and make the deletions.
If it would be easier, I can even do a system call and use SED (v4.1.5) and/or AWK (3.1.5) instead.
I want to know the Perl command to replace a string by pointing the line number. I know how to replace a string without pointing a line number but I am in need to replace only the two matching string in a file

At the moment I have a flat file which is being used by a few people. I want a script to remotely change the file, so I can start logging who is doing what.At this point here is one requirement I am trying to develop.

View 1 Replies View RelatedI wanted to find and replace a string from a perl file. I have written a script in bash which runs the following command.
perl -pi -e "s/$findstring/$replacestring/" testfile
where as $findstring = print F_WC_TMP"$line
";
and $replaceString = $line = join ' ', split ' ', $line; print F_WC_TMP"$line
";
But when I am running the above command, i think it is replacing the $findstring with the above mentioned string and hence it contains a $line, it is looking for the variable $line and not finding the exact string. I am confused about how to search for a string that contains $ in it and replace it with another $string.

View 20 Replies View RelatedMy .jar file needs and uses some files in the same directory it's in (everything, including the jar was unzipped into said directory). It runs perfectly when I do java -jar file.jar in the command line, but there's trouble when I double-click the file when running from the file system manager. I've tried a custom command under properties ie java -jar, but the problem is that the .jar file doesn't seem to be able to use any of the files in the same directory. When running, the jar can't find any of the files that it needs.

I have a php file that I need to execute via a cronjob. This file should be run by the www-data user as its a file in my /var/www/project folder. When I run this file under root (php -f cron.php) everything works perfectly, but I want it to run under the www-data to be safe. Before I run it vai crontab I tried it via command line as the www-data user and I receive errors:
Fatal Error: Allowed memory size of 8388608 bytes expired (tried to allocate 232 bytes).
But when I run it as the root user I get no errors and everything works correctly. The file cron.php is used to process automated tasks in my CRM. So I don't really want to have the root user running a crontab every few minutes for this.
Must the www-data user be given more permissions? I am using Ubuntu 6.06LTS
PHP - 5.1.2
Apache - 2.0.55

Running: Red Hat Enterprise Linux Server 5.2 (Tikanga) I need to be able to automate transferring a few files over from one server to another using scp or the sftp protocol. I have received a text file which looks like a key file along with username and passphrase information for the target server in question.
Instructions were given to me to import the provided text file in puttyGen then save the imported key as a private key to be used by scp or sftp. My assumption is this is for windows utilities, which I am not using. My frustration comes in trying to automate logging into this server via sftp or scp to automate some file transfers. I am asked for a password every time because the public and private key methods failed to find my keys. How can I call scp or the sftp utilities and use the provided key file (the one I generated using puttyGen or the original one provided to me) to login to this server? I've tried taking the generated ppk file from puttygen and adding it with the ssh-add command but that still did not work.
I am using an awk command to print a line from a cvs file.the awk command includes an if statement that filter the output-lets say i want to print all the lines that the price field is greater than 30.i have it working when i put the parameters myself.. but when i try to send them with vars it wont work..i am sending the sign of the if statement - can only be: == , < , >it looks like this:
cat file.csv | awk -v sign=">" -v field="2000" '{if($3 sign field) printf "%-12s%-12s%-12s%-12s
",$1,$2,$3,$4}' FS=,
the bold part is the problem , because when i put the sign parameter myself t works great.. i guess its a chars issue but i cant spot it
