General :: Renaming Variables In A List
Mar 14, 2011
I am trying to rename a list of variables in my script using a second list of variables. I want the variables in the second list to replace the variables in the first list such that the first variable in List 1 is renamed after the first variable in List 2, the second variable in List 1 is renamed after the second variable in List 2, the third variable in List 1 is renamed after the third variable in List 2, and so on.
For example:
I know how to rename each file individually, but would like to run Do Loop which can rename all my output files at once.

curl -L http://URL/file[1-2].txt -o $(date +%m-%d-%y) newfilename{1,2}.txt
Basically, this command goes to URL, downloads file1.txt and file2.txt, however it saves BOTH files as newfilename1.txt. I would like the script to name the second download (file2.txt) newfilename2.txt. So, before you say to use the -O switch in Curl, please understand that I wish to rename the files so that they are not what they were on the server (names are too long). So file1.txt becomes newfilename1.txt, file2.txt becomes newfilename2.txt. Is this possible? The command I listed works only until the newfilename{1,2}.txt, it always saves as newfilename1.txt

Is there a command that can list the variables that I am using in a script? I mean the variables that I created in the script not the environment or local variables. For example if I have a script that has the following var's like : name=Alex, age=20, postal_code=12345, how can I list them all @ once WITHOUT using echo $name, $age and so on. Imagine I have a lot of variables and i can't echo them all.

I'm trying to do substitutions to a file based on passed variables.
For example, I have a file called test.txt that has 5 lines:
What I want to do is to go through that file, line by line and check for the presence of a passed variable in that line. If I have a match, then substitute and print, otherwise print line as is. My problem arises in that the number of variables is well, variable.
The code I started with was the following:
Code:
What I was hoping for was test.out to look like this:
What I get is a much longer file like this:
This makes sense after thinking about it but is there anyway to get an output like the first case?

I have a C header file which have arrays of predefined(known) structure type. But i dont have names of arrays and their size. when i include that file and compile my application, i want to know the names and sizesof those arrays.
purpose of application is to get the content of those arrays and to explain it in descriptive words instead of hex numbers.ofcourse this can be done by file pointers and reading also with out header file inclusion, but as i am working in C, once compiled, those variables are in my address space in i include header file.

mkvmerge -o <filename without extension>_TV.mkv -S <filename> && mkvextract tracks <filename> 3:<filename without extension>.*** && perl /home/brian/Desktop/ass2srt.pl <filename without extension>.*** && rm <filename without extension>.***
Doing these commands for multiple command line file inputs is the goal. So I can just type ./script.sh *.mkv in my terminal.This is what I have so far, but it doesn't work whatsoever.

I was wondering is there another way of renaming a file aside from using mv in linux?
For example changing /home/usr/blah.txt to something like -home-usr-blah.txt

What's the easiest way to rename (change the volume label of) a fat16 volume (e.g. on a USB drive) from linux? It seems like mlabel from the mtools package is meant to do this, but the documentation is not geared to rapid assimilation.

What's the command for renaming files? I thought it was "mv"--I typed "info" and read
Quote:
* mv: (coreutils)mv invocation. Rename files. So, desiring to give a .JPG extension to a jpeg file that had no extension (because I dug it out of my Firefox cache), I typed
Quote:
mv '/home/josh/Desktop/Natalie pictures/DEC8FFA5d01' *.jpg
That didn't rename the file; it made the file disappear from its folder. What did I do wrong?

I run a script which generated about 10k files in a directory. I just discovered that there is a bug in the script which causes some filenames to have a carriage return (presumably a '' character).
I want to run a sed command to remove the carriage return from the filenames.
Anyone knows which params to pass to sed to clean up the filenames in the manner described?
I am running on Linux (Ubuntu)
The character causing the filename to 'break up' accross multiple lines appear to be a CR (carriage return) instead of ' '. The filename is being diaplayed in thetitle of a text editor with %0D in the positions of where the file name breaks up. So I need to remove the CR chars from my filenames.

Is there a way to do a batch renames of files that will keep each individual filename, but change it in the way I want?
The specific issue is this. I have a harddrive with something like 1300 movies on it. They're all organized alphabetically, but there are like 200 movies that begin with 'The'. I want to rename all of these movies that begin with The so that the The at the beginning is dropped and added at the end (for example, turn "The Shawshank Redemption" into "Shawshank Redemption, The"). I'd like to do this with a simple command if its possible.

I've been trying (and trying...) to write this script. I'm a complete newbie on bash scripting. This is what I've come up so far:
Code:
./reading
| Number of characters 48
| + Current: 107_david_guetta_-_missing_you_(feat._novel).mp3
| + Changed: 107_david_guetta-missing_you_(ft._novel).mp3
| + Matched: "(feat._" substitute "(ft._"
| + Morping: "107_david_guetta-missing_you_(feat._novel).mp3" to "107_david_guetta-missing_you_(ft._novel).mp3"
'-[END] ....

that works to disallow non-owners from renaming the file, but what I wouldlike to do is disallow EVERYONE ( including the owner of the file ) fromediting, moving, or changing the filename once it is created. the only personwho should be able to make those changes is a special user.

We are having 12 windows computers xp which are connected to a linux machine which has samba server installed on it for backup purposes of these 12 windows users. We want the like this , that a user copy a folder from their local machine and paste it to the samba server . but they cannot delete this folder once the backup is there at linux machine.
So this is working fine. But our users are able to Rename the folder they have pasted at linux machine which we dont want . and even they are able to cut and paste files from 1 folder to another folder in the samba server. We just want them to copy a file or folder from their local windows machine and paste to samba server and they can also read it (copy and paste back to their windows computer)whenever they want . but we dont want them to cut and paste within linux machine and rename that file as well.

I want to rename files in multiple subfolders with a prefix (e.g., rename "file.tif" with "prefix_file.tif") and not have to be in the subfolder.
code: for f in /path/to/*; do echo mv "$f" "PRE_$f"; done
gives you this: mv /path/to/file1 PRE_/path/to/file1
instead I want this: mv /path/to/file1 /path/to/PRE_file1

Recently I installed Dropbox on a server to do file synchronization and it added " (Case Conflict 1)" to a whole bunch of my files! I realize now that it was caused by case insensitivity but I'm still left with hundreds of files that are in this renamed state. Is there a script in Linux that would allow me to recursively go through the directories and strip out this string?
i.e.
a (Case Conflict 1).jpg --> a.jpg
/myfolder/abc (Case Conflict 1).doc --> /myfolder/abc.doc
/myfolder/subfolder/mydoc (Case Conflict 1).pdf --> /myfolder/subfolder/mydoc.pdf

How can I copy multiple files, each with a slightly different name from the SOURCE in the same directory?
Example: '/home/junk' contains A.txt, B.txt
I want to copy /home/junk/A.txt to /home/junk/A1.txt and /home/junk/B.txt to /home/junk/B1.txt using a single command.

Basically I need to rename a bunch of .doc files using the for-structure and the mv command (w/ wildcards) in bash. I guess this would be a bit easier if I'd use the rename command, but since this is a school assignment of sorts I need to use for & mv. The .doc files are named "1filename.doc", "2filename.doc" etc. And I've got to rename them to "aaa_1filename.doc", "aaa_2filename.doc", "aaa_3filename.doc" and so on. Tried to dabble quite a bit with the for and mv commands, basically just got a bunch of errors. Every damn time. For 2 hours. The most common error was "mv: missing destination file operand after ..."

I have some random files in a folder. I want to rename all of the files in a batch process. I have a text file that contains the Currentname of all the files in the folder, as well as a text file with all of the Newname of files in the folder. I want to replace Currentnames with Newnames.
For example, here are the names of the files in the folder:
1.mp4
2.mp4
3.mp4
I have a text file with the Currentname of all the files in the folder:
1.mp4
2.mp4
3.mp4
I have a text file with the proper Newname of the file:
a.mp4
b.mp4
c.mp4
I want to rename Currentname with Newname in the folder. So when I go to the folder the Newname of the files are:
a.mp4
b.mp4
c.mp4

i have inherited a mixed bag of sorts: several xp users updating an access mdb with the BE on a lamp stack shared via samba. i have a backup device which gets mounted at: /media/disk... each client record (has) a folder by the companyname on the samba share, and all relative documents are placed there. when the backup script runs, it just copies newer or missing files.
someone has been renaming folders, and not matching the folder name to the related companyname from the mdb. so...the backup script captures and duplicates the data in the renamed folders. some client records also have periods in the name (not required from a data pov), such as 'Company Ltd.' instead of 'Company Ltd'. i can produce a list of company names as the folders should be found easily enough, but get a little stuck with the linux scripting.
i can easily remove and further prevent any unwanted punctuation in the company name on the client record, and create the correct folder name on the samba share with vba, but would also like to:
-for each 'client activity' folder on the backup device
-rename the folder by removing punctuation marks
or
-delete the folder if is a dupe
i tried: ls -al | grep '&' - it properly returns only those lines with an ampersand in the folder name, but returns all folders when i try that with a '.'.
what would be the easiest method to do the renaming? i thought if there was a way to change ownership of the mounted device, then the vba code (easy to write) would be simple.
OK - i just ran chown -R on the external device, changing ownership to (me) instead of root. didn't want to because it took too long, but can now use the MoveFolder method of the filesystemobject from my app to do the renaming instead of some sort of bash script (which i was dreading).

Today i am trying to learn how to use sed. I set up a testing folder with the following files:
AAb.lol
AAc.lol
AAx.lol
test.sh
My goal is to create a script (test.sh) which renames all the files to their original name without AA. I want to end up with this:
b.lol
c.lol
x.lol
test.sh
sed seemed to be the perfect tool so i went ahead and created a script which i think should clear the job.
[Code].........
mv: missing destination file operand after `$i' From that 2nd line i can tell that $NewName is just empty. I also read something about sed needing the -e option for scripting purposes but i just don't understand it.
