I am trying to strip the numbers from the 5th columns and just get letters - in perl - i tried using subsrt, chop. and a regex -
what i want to get is:
i tired appending a regex perl -nle 'print /(w{1,20})d{1-20} but it did not work.
Any way to show the permissions with numbers (777) instead of with letters (drwxrwxrwx) using "ls" command or any other command ?
View 2 Replies View RelatedI have a program that prints out lines like:
And I want to be able to pipe it to sort on that third column, by letter first, then number. But I keep coming getting files sorted like:
(field separations all start at same place, so columns are not jagged like above.)
I have read the sort man pages, and have tried -n for the numbers, and -k for the position to start sorting, among other things. I also tried inputting a second position to start sorting, which sort should supposedly refer to if the two entries are identical at the first place being compared, but it seems to just ignore the second one. I just can't get it to sort the numbers properly...
For now I am manually opening the file in emacs and changing them around, needless to say, very time consuming.
After the completely new installation of Fedora 15 the letters are ugly in comparison with FC 14, no matter which font. It doesn't help to set anti-aliasing manually. The edges of the letters leave blurring.

If yes, return true. If not, return false. In the above example, all the letters (A and D) in string 1 are also present in string 2, so I return true.

View 13 Replies View RelatedI've got a bunch of PDF files that have been produced two "real" pages to a single PDF page; I'd like to chop these in half and put each half on a separate page. Essentially, I need something thatdoes the exact opposite of pdfnup (or psnup). Google and apt-cache search are giving me no love.Platform is Linux, open source preferred; as I've got a great pile of these to do something that can be scripted (as opposed to a GUI) would be nice, so I can just give it a list of them and have it chew away.A pre-existing script isn't the only option, either; if there's sample code to manipulate PDFs in similar ways with a third-party library, I can probably hack it into doing what I want.

View 3 Replies View RelatedOne of my application generates a text file with an XML output in it. I need to read that log files and if the output does not match to a string in couple of tags it should create a log file with the file name and the the tag name.
The two tags where the string should match is:
Identity format tag should always be JPEG , well- formed and valid status tags should be true.
sample output file:
In Perl. I can't find the global variable for $_ (except not $_ it's the one to specify AFTER the matched string.) its dollar sign then something else. Does anyone have a cheat sheet for global symbols?

In my perl script I'd like to test if a string is written in uppercase letters or not. How can I do that? This type of test don't seem to work, so there must be other ways of doing this:

I can create a subroutine that compares each character aginst a list of uppercase letters, but I'm hoping there's allready a build in routine in perl that does this...
I have question about replacing a string in a file.
How can I replace the printerb's 10.1.1.1 to something else(10.1.1.2, for example) without replace printera's 10.1.1.1 accidentally?
I have tried perl -e -pi "s/10.1.1.1/10.1.1.2/g" /etc/hosts. but, perl replace both 10.1.1.1 to 10.1.1.2.

I am new to perl and am having trouble adding some strings together.
My full code is below:
The problem is $NewCommandB is always split into two lines, where the second line contains the "/atlas2/<blah>/<etc>/..." string. Since I am generating a .sh file to execute a lot of similar commands I need the string to all be on one line. Any idea why I get this behaviour and any suggestion on how to tell perl to make $NewCommandB a one line string?

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.
Recently I faced a problem in typing in English in OpenSuse 11.3.When I try to type in English it shows me Greek letter and worse than that I think it is really Greek (not only in font) because when I enter my passwords or try to type a command in terminal I get error,I tested with UK and USA and all other English languages and I still have this problem. I even do reset in my keyboard layout setting and in KDE setting but it didn't help.
