Rename pdf files after their directory name and acoording to their total number

IlIl7 · 07-06-2012, 01:22 PM

Hi
Given:
I have up to 1000 directories:

Quote:

dirA ...dirX ....etc

all of which are located inside the directory

Quote:

~/home/somestuff

Each one of the directories contains more than one pdf file with random names:
e.g.

Quote:

inside directory dirA there are the pdfs: koko.pdf
inside directory dirB there are the pdfs: ppko.pdf pig.pdf
inside directory dirX there are the pdfs: p2p2.pdf asas.pdf gigi.pdf qqq.pdf

Problem:
I need a command/script which when i run from somestuff will rename all pdfs according to both their parent folder name and their total number inside this folder.
That is I need to get:

Quote:

inside directory dirA: dirA.pdf
inside directory dirB: dirB1.pdf dirB2.pdf
inside directory dirX: dirX1.pdf dirX2.pdf dirX3.pdf dirX4.pdf

So far the following script works BUT ONLY IF I RUN IT INSIDE FROM EACH DIRECTORY:

Code:

c=0
for i in *.pdf
do 
   test -f "$i" &&\
   mv "$i" $(printf "${PWD##*/}%03i.pdf" $c) &&\
   ((c+=1))
done

I NEED TO MAKE IT WORK FOR EACH ONE OF THE DIRECTORIES WHEN I RUN IT FROM somestuff
i think its just some change..aint have the experience though

Asserting:
0) no directory names contain spaces or other IFS b0rkage,
1) subdirectories are all in one root (here: /path/to/directories) and
2) at the same level and you
2) mod your function a bit (use 'find' instead of "for i in"),
you could:

Code:

myRename() { c=0; for i in *.pdf; do test -f "$i" && mv "$i" $(printf "${PWD##*/}%03i.pdf" $c) && ((c+=1)); done; }
cd /path/to/directories; find . -type d -maxdepth 1 | while read SUBDIR; do
 cd "${SUBDIR}" && myRename && cd ..
done

No, I don't have a clue what you did as you posted nothing. On the CLI run 'set -vx' before running the whole thing again.
