Rename files to unique names and move them into a single destination directory - bash

Question

i have 100s of directories with same filename of content.html along with other files.
I am trying to copy all these content.html files under 1 directory, but since they have same name, it overwrites each other
so how can i rename and move all these under 1 directory
Eg:
./0BD3D9D2-F8B1-4472-95C2-13319650A45C:
card.png content.html note.xhtml quickLook.png snippet.txt
./0EA34DB4-CD56-42BE-91DA-F631E44FB6E0:
card.png content.html note.xhtml quickLook.png related snippet.txt
./1A33F29E-3938-4C2F-BA99-6B98FD045742:
card.png content.html note.xhtml quickLook.png snippet.txt
command i tried:
rename content.html to content
find . -type f | grep content.html | while read f; do mv $f ${f/.html/}; done
append number to filename "content" to make it unique
find . -type f | grep content | while read f; do i=1; echo mv $f $f$i.html; i=i+1; done
MacBook-Pro$ find . -type f | grep content | while read f; do i=1; echo mv $f $f$i.html; i=i+1; done
mv ./0BD3D9D2-F8B1-4472-95C2-13319650A45C/content ./0BD3D9D2-F8B1-4472-95C2-13319650A45C/content1.html
mv ./0EA34DB4-CD56-42BE-91DA-F631E44FB6E0/content ./0EA34DB4-CD56-42BE-91DA-F631E44FB6E0/content1.html
mv ./1A33F29E-3938-4C2F-BA99-6B98FD045742/content ./1A33F29E-3938-4C2F-BA99-6B98FD045742/content1.html
once above step is successful, i should be able do this to achieve my desired output:
find . -type f | grep content | while read f; do mv $f ../; done
however, i am sure i can do this in 1 step command and also my step 2 is not working (incrementing i)
any idea why step2 is not working??

Answer 1

bash script:
#!/bin/bash
find . -type f -name content.html | while IFS= read -r f; do
name=$(basename $f)
((++i))
mv "$f" "for_content/${name%.*}$i.html"
done
replace for_content with your destination folder name

Answer 2

Suppose in your base directory, you create a folder named final for storing
content.html files, then do something like below
find . -path ./final -prune -o -name "content.html" -print0 |
while read -r -d '' name
do
mv "$name" "./final/content$(mktemp -u XXXX).html"
# mktemp with -u option just creates random characters, or it is just a dry run
done
At the end you'll get all the content.html files under ./final folder in the format contentXXXX.html where XXXX are random characters.
Note:-path ./final -prune -o in find prevents it from descending to our results folder.

The inode of the of the files should be unique and so you could use the following:
find $(pwd) -name "content.html" -printf %f" "%i" "%p"\n" | awk '{ system("mv "$3" <directorytomoveto>"$2$1) }'

Answer 4

I'd use something like this:
find . -type f -name 'test' | awk 'BEGIN{ cnt=0 }{ printf "mv %s ./output-dir/content_%03d.txt\n", $0, cnt++ }' | bash;
You can replace ./output-dir/ with your destination directory
Example:
[root#sl7-o2 test]# ls -R
.:
1 2 3 output-dir
./1:
test
./2:
test
./3:
test
./output-dir:
[root#sl7-o2 test]# find . -type f -name 'test' | awk 'BEGIN{ cnt=0 }{ printf "mv %s ./output-dir/content_%03d.txt\n", $0, cnt++ }' | bash;
[root#sl7-o2 test]# ls ./output-dir/
content_000.txt content_001.txt content_002.txt

You can use shopt -s globstar to grab all content.html files recursively and then use a loop to rename them:
#!/bin/bash
set -o globstar
counter=0
dest_dir=/path/to/destination
for f in **/content.html; do # pick up all content.html files
[[ -f "$f" ]] || continue # skip if not a regular file
mv "$f" "$dest_dir/content_$((++counter).html"
done
