Programming :: Rename Files Recursively, Only Keeping Last X Digits Plus Extension?
Nov 29, 2009
My problem is this:I have a number of directories, all containing files of different name lenghts, including letters, numbers and possibly spaces. I want to recursively rename all of these files, so that only the _last_ 5 digits (not counting the extension) remain. In other words: I want to cut off all but the last 5 digits and not touch the extension.
I've tried to read up on tr, rename (perl version), sed, cut etc. and browsed through some threads here, but so far couldn't quite figure out how to do it.
If someone could point me to the right (standard) CLI tools and syntax.

I have thousands of files in hundreds of sub-directories that need renaming. The files I need to rename all look as below:
Note the .ogg.mp3.
been_all_around_this_world.ogg.mp3
I want to remove the .ogg from the files, so in this one case it would end up renamed looking like this:
been_all_around_this_world.mp3

I'm planning to writing a script to rename files recursively.
To be said that I'm using /bin/sh (not /bin/bash) as this is the only shell available on the busybox of the linux router (tomato) I'm using.
Basically I would like to rename files with extension .jpg using as a suffix the filename of another file in the very same directory with extension .avi
The reason for this is because pretty much all the DLNA devices like modern TV playing .avi files will display a thumbnail of the video when browsing the filesystem, however to do so they'll need .jpg image wit hthe same filename of the video in the very same directory.

I need a either a script or perl script that will allow me to mass rename files, folders, and sub folders. I need to replace special chars in the current file names with underscores. I was able to make this happen in a single directory, but not recursively.
Here is what does it in a single directory.
for file in *
do
mv "$file" $(echo "$file" | sed 's/[^A-Za-z0-9_.]/_/g')
done

I have a bunch of files on a Ubuntu box, which have various characters in their filenames that Windows doesn't accept (mostly ":" and "*", but possibly others).What's the simplest way to get these all renamed and moved to a Windows machine? It's OK to replace these characters with something like "[colon]" and "[asterisk]".

I am trying to rename a lot of files but need to keep the extension :
the files are films names :
a.b.c.d.***.iso
the result should be replacing "." by spaces " "
this command :
for files in *.iso ; do mv "$files" `echo "$files" | tr '.' ' '`; done
put a space also before the extension iso ??
How can I rename files from
"a.b.c.d.iso" to "a b c d.iso"

I am to rename all the files within a directory (which contains multiple subdirectories) recursively without invalid characters.
I tried the coding posted above.
find . -type f -printf '%p
' | while read file; do
oldfile=$(basename "$file")
newfile=$(echo "$oldfile" | sed 's/[^A-Za-z0-9_.]/_/g')
if [ ! "$newfile" == "$oldfile" ]; then
echo mv "$file" "${file%$oldfile}$newfile"
code....
but I get an error on both of them stating "find: bad option -printf find: [-H | -L] path-list predicate-list"

I am hoping someone already has a script or knows of an app that will let me do this fairly easily - I have a fairly large folder structure that goes several levels deep, etc. In many cases there are duplicate file names that are not really different, e.g.,
/home/chris/folder/folder1/doc1.doc
/home/chris/folder/folder2/folder3/doc1.doc
I want to recursively go through /home/chris/folder and move everything to /home/chris/another_location/ without subfolders and renaming duplicates as appropriate, e.g.,
/home/chris/another_location/doc1.doc
/home/chris/another_location/doc1_1.doc

I have a directory listing with many subdirectories having many files. I want to recursively search for the oldest 5 files starting from the base directory and not 5 from each subdirectory. I am writing a shell script which sorts them using ls -lRtur|egrep "txt|jpg" > /tmp/file1 Now from this /tmp/file1 file I want to sort the files same as what the ls -ltr command does that is oldest file time to newest file time first. How do I sort based on Linux time stamp? The files itself also have Linux timestamps embedded in them So I can sort based after extracting them as well if it is easier.
My /tmp/file1 has entries like below.
-rw-rw-r--. 1 usr1 usr1 705 2010-01-22 17:25 sample20100603173659.jpg
I want to get the 5 oldest files and then delete them.

Is there a way, preferably in python or BASH, to rename files from a list? for instance, track1.mp3, track2.mp3 should be renamed to the names stored in a file listing song names. I have tried to loop a variable through directory listing and renamed them, only to find that filenames with spaces can't be assigned to a variable as a whole. To solve the problem above, I have tried the read command in BASH, which enables the program reading line by line from a list. However, It was failed to pipe the results from directory listing to the read command.

I was hoping to get some pointers on how to rename files based on database entry. I got hundreds of thousands of files that has GUID name assigned to it. only way to find out the file name is to look up the database table. Its obvious that this is not efficient. I couldn't find any tutorials on how to do this. Please point me to right direction. A starting point would be very helpful.

How do you rename:
abc123.txt
abc124.txt
abc125.txt
to
abc.txt.123
abc.txt.124
abc.txt.125
Basically, I want to move the digits from the filename to after the extension.
It works for one file if I type:
rename 123.txt .txt.123 abc.txt.123
but I have thousands of files like these.

I have scowered the internet for the answer to this one. I need a script to rename multiple files to the same exact name, run a program on the file then do the same for the next file. We have a unix backend system that is expecting to load the file with the filename of cards.in So I will have files named card.2009xxx, like i said i will have around 4 or five of those. I want the script to rename card.2009xxx to cards.in, run our unix program on cards.in which inturn changes the file name and once complete i want the script to rename the next cards.2009 to "cards.in"Until there are no more left in the directory and the unix program has processed all the files. All of this is occurring in the same directory. I have written some scripts but they fail by moving for example cards.200901 to cards.in then immediately moving cards.200902 to cards.in and that is not good because it is overwriting valuable data

I'm having a hard time trying to get the number of digits in a uint64_t variable. The reason I'm using this is I want to make sure I get x amount of digits inside of a variable before I use it, but since the higher the digits, the better the program is.I currently use the following code, and it works, but my loop will never exit because the length is always 0:
Code:
/**
* numbdigits()
* number: The number to evaluate [in]
*
* Returns the number of digits found in a number.
[code]....
getrand() returns a uint64_t as well (and works). The only way the while() loop ends without my intervention is if I do curd += numdigits(val) instead...but, that gives a false value as well.

I'm writing a bash shell script that among various other things will traverse through a directory with hundreds of files and rename those who match a pattern found in a config file. It's expected that only about one in ten files will actually match, and those who don't, will simply just be ignored for this purpose.
This should for instance cause the file "dBase program file December 1987.prg" to be renamed "Clipper source code December 1987.prg", and conversely "C++ source August 1996.cpp" to be renamed "C source code August 1996.cpp" etc.A sample file such as "Random Data File.dat" should not be renamed here since it's not mentioned in the config file..What is the quickest, most elegant way to do this in bash?I am thinking of using bash's built-in regex matching combined with the /bin/rename utility, but don't quite know how to get started to catch this..I guess there are plenty ways of doing this in perl and elsewhere as well, but since this has to integrate into a pre-existing bash script, that's what I'm looking for.Anyone out there with a spare moment to offer a hint in the right direction?

The result become 'UsUoUmUeUtUhUiUnUgU' instead of 'somethingUUU' as expected. Looks like my string contains some 'hidden digits' in between the letters. Does anyone have an idea about that?

I am having a huge problem checking the data I input to make sure it is correct. What I am trying to achieve is when I input a value, it will check if the input is all digits and if it is not, check to see if it contains certain alphabets. Thus for example, if I were to input in data such as "11A" , the program will then inform me "There is an important alphabet in the program." This would be my expected output. Here is the program I have wrote...
Code:
int test(string r ){ const int arraySize = 10;
char array2[arraySize2] ={'A','B','E','F','G','H','J','K','N','O','P','Q','R','S','T','U','W','Y','Z'};
for(int cntr = 0; cntr <r.length(); cntr++)
if(!isdigit(r[cntr])){ for(int new1 =0; new1<arraySize2;new1++)
for(int cntr1 = 0; cntr1 <r.length(); cntr1++)
if(array2[new1] == r[cntr1]){ return 2; //will return2 when it finds the same
// char in the array and the string r. } else{ return 3;
//will return 3 when there is a char
//in the string which isnt in the array
} } else { return 1; // will return 1 when string is all digit.
} int main() { string r = "11D"; test(r);
if(test(r) == 1) { cout << "ALL ARE DIGITS" << endl;
} if (test(r)== 2) {
cout << "There is an important alphabet in the program." << endl;
} if (test(r)== 3) { // testRoman(r);
cout << "There is an Alphabet in the String which is not in the Array" << endl;
} }
So, the problem I am facing is when I input in data such as 11 or A , the prog will come out the right input. But if I were to put in data such as "11A" , the output coming out will be "ALL ARE DIGITS". The problem which causes this seems to be in the return statement , as once as it finds the first char which is a digit, it will then return 1 and not continue checking the rest of the string. Is there a way I can stop or continue a loop if it has met the condition I stated? What I can do or any other way available for me to check my input?
