General :: Deleting A File Beginning With '?'

Does anyone know how to do this?

View 1 Replies View RelatedGeneral :: Insert Tab At Beginning Of Each Line In File?
Aug 5, 2010I am trying to create a shell script where a user can specify a file with a list of logins and the script will create a batch file with specific information in specific columns.
Example:
loginfile.txt has
User1
User2
User3
I need the output to be as below:
1 User1 Date 12/31/9999
2 User2 Date 12/31/9999
3 User3 Date 12/31/9999
Where the columns are separated as below.
1[tab][tab]User1[tab]date +%D[tab]12/31/9999
2[tab][tab]User2[tab]date +%D[tab]12/31/9999
3[tab][tab]User3[tab]date +%D[tab]12/31/9999
I can use the nl utility to get the numbers easily enough, but I need two tab separations between the number and the user list. Is there a sed command that will insert at the beginning of each line? If so I can just run nl after I get some tabs up in the front.
General :: Filename Beginning With Left Bracket: File Cannot Be Erased
Nov 28, 2010Kernel 2.6.21.5, Slackware 12.0
I saved a page from Linuxquestions. It was saved under a filename beginning with '[' (left square bracket). And I now can't delete the file. Unfortunately I cannot send you a screenshot because opening a terminal in the GUI makes ls behave differently. I shall try to describe, assuming the file is in dir '.'. Also let '[SOLVED]foo.html' be the file in question:
Code:
$ ls
<the file is listed>
$ ls [*
/bin/ls: cannot access [*: No such file or directory
$
If I want the hdd to get rid of this file, what should I do? Any hint will be welcome.

Ubuntu :: Deleting File With '' In The Name
May 27, 2011I tried running a back-up/restore script in a WordPress install to migrate from one server to another... long story made short, I ended up doing it manually and all is well on that front
The one remnant from that botched script is that it tried creating a directory 'wp-backup' and then a file inside that directory - but it tried using '' instead of '/'. So what it created was a file named 'wp-backupindex.php' with a file size of 0 bytes.
The problem is thus: I can't change the permissions nor delete the file, because of the invalid file name. I don't have direct shell access (that cost *extra*, of course) and every time I try with the web-based file manager (Quixplorer) it sees it as 'wp-backupindex.php', as though the '' is acting as an escape sequence in the file name. Same thing in FileZilla, I can't do anything to the file without it complaining about the invalid file name.
how to ixnay this one file given the limitations above (no shell access) short of calling and bugging tech support to delete the file for me?
General :: List Files Beginning With Underscores First When Using `ls -l`?
Aug 3, 2011I'm using ubuntu (natty), and when I use ls -l, the files are listed, but apparently the sorting algo ignores any special characters. For ages I've used underscores to mark special folders. And it seems to me, that they were always listed first. Now, the underscore is completely ignores. Let's assume that I have the files fileA, _fileB and fileC in a folder. Currently, ls -l orders them like so:
malbert@dredg:/tmp/1$ ls -l
total 0
-rw-r--r-- 1 malbert domain users 0 2011-08-03 15:27 fileA
-rw-r--r-- 1 malbert domain users 0 2011-08-03 15:27 _fileB
-rw-r--r-- 1 malbert domain users 0 2011-08-03 15:27 fileC

I've dug through the ls man page and could not find anything. Is there somewhere a system-wide collation option? Or something the like?

Apr 1, 2009Was 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.

Programming :: Deleting Unwanted Characters In File
Mar 31, 2010Currently, I'm working on personal project. and I'm kinda stuck. What I want to do is that open a file, and edit that file (deleting unwanted characters). The problem arises after I deleted unwanted characters, the file still has the same length of the original one. Let's assume that we have a file with "1234" in it. I deleted "3" ( I overwrite "\0" ) so now when I check the file, it's 124. But when I check the length, the both have the same size as 4
Here is an example source code
int length, length2;
num = open("a.dat", 2)
length = lseek(num, 0, 2); // Initial length
lseek(num, 2, 0); // editing
write(num, "\0", 1);
length2 = lseek(num, 0, 2); // Final length
close(num);
When I print those values those are exactly the same. Length2 should be one less than length, but the both are 4. What's wrong in m code? Am I supposed to use different character rather than "\0"?
General :: Mplayer Just Starts Playing The Audio Stream From The Beginning?
Mar 18, 2010I have and avi file and an ac3 file that contains an alternate audio stream. I run mplayer like: mplayer -audiofile foo.ac3 bar.avi
mplayer takes the audio stream from the ac3 file as expected, but when I try to scroll the video using arrows or pgup/pgdown keys, the audio gets desynced: mplayer just starts playing the audio stream from the beginning. Do I have to pass any additional command line arguments in order to make it scroll properly without desyncing audio?
General :: Sed Command - Find Line Not Beginning With Double Quote
Mar 15, 2011I need to find each line in a file which does NOT begin with a double quote (") and append that line to the previous line. I have been successful doing this using the following command:
cat filname.csv | sed -e :a -e '$!Ns/
[^"]//;ta -e 'P;D' > newfilename.csv
My issue is the substitution. As you would expect after the line is appended to the previous line the first character is removed. I need it to not be removed. I tried:
cat filname.csv | sed -e :a -e '$!Ns/
[^"]/&/;ta -e 'P;D' > newfilename.csv
but it just hangs.
Goal:
Input:
"line 1"
line 2
Output with existing sed command is:
line 1ine2
I need it to be line1line2.
