So,
hopefully this is the right section to ask this in!
I'm looking to remove everything before in a txt file so long story short i've made a number wordlist with Crunch im basically wanting to remove all the unless numbers to numbers i want to start with.
so everything before 1232120000 i want to remove from the txt file i've heard you can do it with sed or awk im not familiar with using sed or awk.
1) deleting file using remove() call
2) no other hard link for the file
3) tried to close file descriptor using following scripts then remove() call
-------
for fd in $(ls /proc/$$/fd); do
case "$fd" in
0|1|2|255)
;;
*)
eval "exec $fd>&-"
;;
esac
done
-------
But space not freed
4) I tried with truncate() and then remove() call Now files deleted and space freed
Is it the only and right way to do this?

Thank you!
Hello,
I would like to remove those files:
MyDir/boo.tmp
MyDir/.zip.tmp
rm MyDir/*.tmp removes only boo.tmp but not .zip.tmp (No such file or directory).
I want to be able to remove any file that finishes with the .tmp extension even if the filename starts with . something.tmp
Thanks for your help :}
I wanted to delete a couple of files, so I did. Then I noticed that they were "write-protected". What does that mean? Why was I able to delete the files considering I wasn't the owner and the files did not have group write permission?
Code:
[Michael@devserver backup_database]$ ls -l
total 4344
-rw-r--r--. 1 apache apache 50639 Feb 6 05:42 2015_02_06_05_42_01.sql
-rw-r--r--. 1 apache apache 654623 Feb 6 05:45 2015_02_06_05_45_54.sql
-rw-r--r--. 1 apache apache 3738269 Feb 6 05:49 2015_02_06_05_49_02.sql

Hello everyone,
Although it seems easy, I've been stuck with this problem for a moment now and I can't figure out a way to get it done.
My problem is the following:
I have a file where each line is a sequence of IP addresses, example :
Line 1: 10.0.01 10.0.0.2
Line 2 : 10.0.0.5 10.0.0.1 10.0.0.2
...
What I'd like to do, is to remove lines that are completely matched in other lines. In the previous example, "Line 1" would be deleted as it is contained in "Line 2".
So far, I've worked with python and set() objects to get the job done but I've got more than 100K lines and sets lookups are becoming time consuming as the program goes :/
Thanks for you help
Hi,
I'm very new at this. This is probably to long. This is the first time I've posted a question in a forum like this. Don't know yet how to state this kind of problem concisely.
-The problem: my Linuxmint Rebecca 17.1 won't boot up. I believe I deleted an essential file from the OS and need to reinstall Rebecca. But, here's the big thing I feel desperate about. I need to do this (reinstall) without destroying (overwriting, erasing or such) all my data, and thus losing all my research and writing project files, audios and so on, my life.
-From my newbie view, very incomplete view,, here's what I think I was doing just before the catastrophe.
-I got a dialog box telling me I had twenty packages that were broken.
-I tried several things involving the update manager, which I can't remember now, to resolve the broken package thing.
-I kept getting a dialog box asking me, in effect, if I wanted to remove these broken packages, which I thought I should probably do.
However, one of these broken packages/files was labeled as an 'essential file.' And, the dialog box asked, in effect: "Are you sure you want to remove this essential file?"
Well no, of course, I didn't want to remove an essential file, so I spent an hour or so trying to get that 'essential file' off that broken package list. I couldn't find a way to do it.
Finally, super frustrated, I went ahead and removed all the broken packages, and along with those, the 'essential' file. (this was the mistake, a huge mistake on my part).
-And ta da. No more Rebecca. I exhausted every approach I know to reboot, but it wasn't going to happen. Quess the 'essential' file I removed was 'essential.' :-).
-I put Rebecca on a USB. Finally got the BIOS to boot up the Rebecca USB. So, I can run Rebecca from the USB. It looks like I could install her again on my desktop from this point. But, I don't dare, without knowing how to do so without further shooting myself in the foot.
Any direction? I would be so grateful if there was. Thanks
I have a log file with a header (which I can skip with awk), and a footer, which I need to find a way to remove. The goal is to extract the middle lines from a file. Specifically, there is a header (1 line) and a footer (1 line).
The only way I can figure out how to do this is if I already know how many lines are in the file to begin with. For example, if the file looks like this:
line 1 (header)
line 2 (interesting line)
line 3 (interesting line)
line 4 (footer)
I just want to extract the middle "interesting lines" without the header/footer lines.
I can't use grep to remove the header/footer, because I don't know what those lines will contain, only that they exist and are exactly 1 line each. In general, I don't know how many lines are in the file.
