I have a bunch of folders that I would like to rename all the files contained within minus any subdfolders.
For example lets say I have two parent folders:
ParentFolder1 - [PF1]
ParentFolder2 - [PF2]
Each parent folder has various amounts of subfolders:
SubParentFolder1_1
SubParentFolder1_2
SubParentFolder2_1
Inside the ParentFolder and each SubParentFolder there can be files such as .mp3, .txt. etc. or more subfolders.
How would I go about renaming all and any files in this manner:
example.mp3 -> example - [PF1]
example.txt -> example - [PF2]
example.docx -> example - [PF2]
Appreciate any input!
This is a way to list files (not folders) in a range of directories and then do something with them... Specifics of renaming are up to you.
for FOLD in Parent*;
do for FILE in $(ls -p $FOLD | grep -v "/");
do echo "$FOLD/$FILE" "$FOLD/${FILE%.*}";
done; done;
Explanation:
For each folder (FOLD) in directories matching the wildcard Parent*,
list the contents, adding / to the end of directory names.
Do inverse grep on that list, leaving just the file names.
Loop through each FILE and echo out the original folder+file, followed by the folder and file with the suffix removed by patten matching.
Once you test this, you can replace echo with mv to do the actual renaming... (I've put these on separate lines to make them more readable, but would usually run this as one long command.

A Redditor had written me a great script that allowed me to move all the files in a series of folders into a new subdirectory in all those folders called New. However, I also have pre-existing folders (namely just 1 called "Journals") that have had their files moved into a subdirectory called New, as well.
How would I modify the following script (on Windows) to not touch any folders within the folders, or perhaps not touch any folder called Journals?
For example, the current directory looks like:
Parent/Folder name/tons of files/
Parent/Folder name/Journals/tons of files
(folder name = random string of alphanumeric numbers in the thousands). Each folder has a ton of files, and a folder called Journals.
I would like:
Parent/randomstring folder/New/tons of files/
Parent/randomstring folder/Journals/tons of files
The code they wrote for me:
# Run from search root
cd "O:\..."
# Change this to taste
export NEWDIR=New
find . | egrep '(mp4$|jpg$|png$)' |
while read FILE
do
BASEDIR=$(dirname "$FILE")
mkdir "$BASEDIR/$NEWDIR" > /dev/null 2>&1
mv "$FILE" "$BASEDIR/$NEWDIR"
done
This code would do the following:
Parent/randomstring folder/New/tons of files/
Parent/randomstring folder/Journals/new/tons of files
I have a problem that I want to know how to do it automatically in bash:
I have 12 folders(0,1,2,3..11), each contain two files like shown below, for example, in folder 1, it contains:
4DNFI6E4RZ9H.fastq.gz
4DNFIIN1NES7.fastq.gz
and none of the files in the folders share the same name.
I want to create a script that can loop into each of the folders, and rename the files according to the name of the folders, for example for files in folder 1, I want the two files to be renamed to:
1_R1.fastq.gz
1_R2.fastq.gz
for files in folder 2, I want the two files to be renamed to:
2_R1.fastq.gz
2_R2.fastq.gz
...
So how to do it? thanks a lot!
Like this :
#!/bin/bash
for dir in */; do
c=0
for file in $dir/*; do
mv "$file" "${file%/}_R$((++c)).fastq.gz"
done
done
ls *
What I am currently struggling is to create multiple files and storing it into each directory.
I have made 100 directories like this:
mkdir ./dir.{01..100}
What I want is to create 100 text files for each directory. So that the result will show like:
click on dir.01 at home dir, which has files named: 01.txt to 100.txt
Also, I want to compress all 100 directories, each containing 100 text files into one using tar.
I am struggling with:
creating 100 text files each in 100 directories
using tar to zip all 100 directories together.
I am more interested in making creating 100 text files IN 100 directories. Also I am MUCH MORE interested in how to use tar to join all 100 directories together in specific file (fdtar) for instance.
If you are fine with empty files,
touch ./dir.{01..100}/{01..100}.txt
If you need each file to contain something, use that as the driver in a loop:
for file in ./dir.{01..100}/{01..100}.txt; do
printf "This is the file %s\n" "$file">"$file"
done
This could bump into ARG_MAX ("argument list too long") on some platforms, but it works fine on MacOS and should work fine on any reasonably standard Linux.
Splitting the loop into an inner and an outer loop could work around that problem:
for dir in ./dir.{01..100}; do
for file in {01..100}.txt; do
printf "This is file %s/%s\n" >"$dir/$file"
done
done
If I understand you need two things. First, you have 100 directories and need to create a file in each. With a for loop in bash run from the parent directory where all other directories you have created are:
for n in dir.*
do
f=`echo $n | sed s/dir\.//`
echo "This is file $n" >"$n/$f.txt"
done
Regarding tar that is even easier because tar will take multiple directories and glue them together. From the parent directory try:
tar cvf fd.tar dir.*
The c option will create the archive. v will tell tar to print all it is doing so you know what is happening. f directories.tar will create the archive with that name.
When you undo the tar operation, you will use:
tar xvf fd.tar
In this case x will extract the contents of the tar archive and will create all 100 directories for you at the directory from which you invoke it.
Note that I have used fd.tar and not fdtar as the .tar extension is the customary way to signal that the file is a tar archive.
I have a huge list of files, they came through different processes, so for some reason the ones in the first folder are numbered like this
A9.txt A1.txt while the ones in the other have A00009.txt A.00001.txt
I have no more than 99837 files so only four "extra" 0 on one side.
I need to rename all the files inside one folder so the names matches. Is there any way to do this in a loop? Thanks for the help.
You should take a look at perl-rename (Sometimes called rename) Not to be confused with rename from util-linux.
perl-rename 's/\d+/sprintf("%05d", $&)/e' *.txt
The above script will rename all .txt files in a directory to the following:
A1.txt -> A00001.txt
A10.txt -> A00010.txt
Hello225.txt -> Hello00225.txt

I have a bunch of files I'm trying to organize quickly, and I had two questions about how to do that. I really appreciate any help! I tried searching but couldn't find anything on these specific commands for OSX.
First, I have about 100 folders in a directory - I'd like to place an folder in each one of those folders.
For example, I have
Cars/Mercedes/<br>
Cars/BMW/<br>
Cars/Audi/<br>
Cars/Jeep/<br>
Cars/Tesla/
Is there a way I can create a folder inside each of those named "Pricing" in one command, i.e. ->
Cars/Mercedes/Pricing <br>
Cars/BMW/Pricing<br>
Cars/Audi/Pricing<br>
Cars/Jeep/Pricing<br>
Cars/Tesla/Pricing
My second question is a little tougher to explain. In each of these folders, I'd like move certain files into these newly created folders (above) in the subdirectory.
Each file has a slightly different filename but contains the same string of letters - for example, in each of the above folders, I might have
Cars/Mercedes/payment123.html
Cars/BMW/payment432.html
Cars/Audi/payment999.html
Cars/Jeep/payment283.html
Is there a way to search each subdirectory for a file containing the string "payment" and move that file into a subfolder in that subdirecotry - i.e. into the hypothetical "Pricing" folders we just created above with one command for all the subdirectories in Cars?
Thanks so much~! help with either of these would be invaluable.
I will assume you are using bash, since it is the default shell in OS X. One way to do this uses a for loop over each directory to create the subdirectory and move the file. Wildcards are used to find all of the directories and the file.
for DIR in Cars/*/ ; do
mkdir "${DIR}Pricing"
mv "${DIR}payment*.html" "${DIR}Pricing/"
done
The first line finds every directory in Cars, and then runs the loop once for each, replacing ${DIR} with the current directory. The second line creates the subdirectory using the substitution. Note the double quotes, which are necessary only if the path could contain spaces. The third line moves any file in the directory whose name starts with "payment" and ends with ".html" to the subdirectory. If you have multiple files which match this, they will all be moved. The fourth line simply marks the end of the loop.
If you are typing this directly into the command line, you can combine it into a single line:
for DIR in Cars/*/ ; do mkdir "${DIR}Pricing"; mv "${DIR}payment*.html" "${DIR}Pricing/"; done
