I have several files in a folder with extension .img and I have only one file with extension data.txt
What I need is to copy data.txt and rename it as the names of the .img files.
For instance for the first file in my folder:
`Meaurmen_2154_data.img` >>> copy data.txt >>> rename it Meaurmen_2154_data.txt
Now I have :
Meaurmen_2154_data.img
Meaurmen_2154_data.txt ## the content is the same as data.txt
and do the same for all other files. The content of he text files will be the same for all files just we change the name according to the .img files in my folder.
Run this script
#!/bin/bash
imageFiles=( *.img );
for i in ${imageFiles[*]}
do
withoutExtension=${i%.img};
cp data.txt "$withoutExtension.txt";
done
inside the relevant directory and it will do it for you.
Try
for i in *.img; do cp data.txt $i.txt; done
rename 's/.img.txt/.txt/' *.img.txt
In some distro's rename is different, requiring
rename .img.txt .txt *.img.txt
As always, you might find yourself in need of installing additional packages.

I have a zipped folder : folder.zip, the zip contains file1 and file2. I want to unzip file1 without unzipping folder.zip (Like what we can do using WinRaR). I want to be able to do this scenario using command line :
open (Without unzipping) folder.zip and display content
Find file1 inside folder.zip
Unzip file1
Get at the end file1 unzipped and folder.zip
I tried to do it using WinRaR application, and I'm expecting to do it using command line.
Did you try unzip folder.zip my/file/in/folder/file1 the/other/file/in/folder/file2?
I tried unzip zipfile.zip '*/file1.txt' and it works. Thank you!
Here, (on linux)
there is an existing archive named A.zip, which include File1 and File2:
A.zip:
File1
File2
and I run this command: zip A.zip File1 File3, then the archive A.zip becomes like:
A.zip:
File1
File2
File3
however, what I really want to get is a brand new archive A.zip! like:
A.zip:
File1
File3
I know it can be done by run rm A.zip and then run zip A.zip File1 File3, but it is not elegant and if I write these commands into a shell script so A.zip may not exist while the action to remove a non-existent file is not elegant as well.
Is there any options for me to get this done?
Use these option to works:
zip -FSr A.zip File1 File3
OPTIONS
-FS
Synchronize the contents of an archive with the files on the OS. Normally when an archive is updated, new files are added and changed files are updated but files that no longer exist on the
OS are not deleted from the archive. This option enables a new mode that checks entries in the archive against the file system. If the file time and file size of the entry matches that of
the OS file, the entry is copied from the old archive instead of being read from the file system and compressed. If the OS file has changed, the entry is read and compressed as usual. If
the entry in the archive does not match a file on the OS, the entry is deleted. Enabling this option should create archives that are the same as new archives, but since existing entries are
copied instead of compressed, updating an existing archive with -FS can be much faster than creating a new archive. Also consider using -u for updating an archive.
For this option to work, the archive should be updated from the same directory it was created in so the relative paths match. If few files are being copied from the old archive, it may be
faster to create a new archive instead.
Note that the timezone environment variable TZ should be set according to the local timezone in order for this option to work correctly. A change in timezone since the original archive was
created could result in no times matching and recompression of all files.
This option deletes files from the archive. If you need to preserve the original archive, make a copy of the archive first or use the --out option to output the updated archive to a new
file. Even though it may be slower, creating a new archive with a new archive name is safer, avoids mismatches between archive and OS paths, and is preferred.
-r
Travel the directory structure recursively; for example:
zip -r foo.zip foo
or more concisely
zip -r foo foo
In this case, all the files and directories in foo are saved in a zip archive named foo.zip, including files with names starting with ".", since the recursion does not use the shell's file-
name substitution mechanism. If you wish to include only a specific subset of the files in directory foo and its subdirectories, use the -i option to specify the pattern of files to be in‐
cluded. You should not use -r with the name ".*", since that matches ".." which will attempt to zip up the parent directory (probably not what was intended).
Multiple source directories are allowed as in
zip -r foo foo1 foo2
which first zips up foo1 and then foo2, going down each directory.
Note that while wildcards to -r are typically resolved while recursing down directories in the file system, any -R, -x, and -i wildcards are applied to internal archive pathnames once the di‐
rectories are scanned. To have wildcards apply to files in subdirectories when recursing on Unix and similar systems where the shell does wildcard substitution, either escape all wildcards
or put all arguments with wildcards in quotes. This lets zip see the wildcards and match files in subdirectories using them as it recurses.
I have a lots of file names under a folder '/files' ,the extesnions of these files are appended with timestamp when that file was created,somthing like abc.csv_20170329. I want to change the extension of all these files to abc.csv_20170330 using the rename command in OSX using the terminal.Can any one help me with the exact command to do that i tried using
$ rename -S '.csv_' .csv_20170330 '.csv'
but this does not work.
for file in abc.csv*
do
mv "$file" "$file__20170330"
done
I have a tar file called test.tgz , inside it are the following files:
tool.foo
atest.you
btest.you
ctest.you
t.you
I want to rename the files inside test.tgz to be:
0.foo
0.you
1.you
2.you
3.you
Without the use of extracting the files and repacking them. How could I accomplish this?
Even though you can't rename the files in the tar archive, you can rename them with a sed expression on the fly while they are being extracted. The option to tar is--transform [sed-expression].
You do need to extract the files before you rename them. When files are in a tgz, they are protected from change.
Say I have a bunch of files in folder A:
1.txt
2.txt
3.txt
...
And a bunch of files in folder B, with the same names.
I want to move all the files from folder B into folder A, without losing any files. This means that some files need to be renamed. E.g., to 1cp.txt, 2cp.txt, 3cp.txt, ...
As I understand it, using
cp folderB/*.txt folderA/
will overwrite all files in folder A. Whereas, if I use the -n flag, this means that nothing will be copied, because -n prevents overwriting.
Does anyone know how I can achieve this copy and rename procedure, so that all files from both folders are retained?
You can use -b (backup each existing file). --backup accepts arguments to control behavior.
Otherwise you can create a bit more lines and check for your files in a more elaborated script.
First, you can rename it.
$ rename -n 's/\d{5}(\d{3})\.JPG$/BeachPics_$1\.jpg/' *.JPG
00000123.JPG renamed as BeachPics_123.jpg
00000124.JPG renamed as BeachPics_124.jpg
00000125.JPG renamed as BeachPics_125.jpg
and then copy it.
cp folderB/*.txt folderA/
