[SOLVED] Changing one word in filename to uppercase

musonio · 12-18-2009, 04:13 AM

I have a large collection of files (pdf books).
I would like to mass rename them like this:

In:
Gilbert, Machiavelli and Guicciardini.pdf

Out:
GILBERT - Machiavelli and Guicciardini.pdf

Is there a way to do this automatically, perhaps with sed or tr?

Thanks in advance.

Bash 4.0

Code:

for file in *.pdf
do
    front=${file%%,*}
    front=${front^^} #change case to upper
    back=${file#*, }
    newname=$front-$back
    mv "$file" "$newname"
done

ghostdog74 beat me to it (is it correct? -> it is now, after editing

):

Here's mine:

Code:

/bin/bash

ls *.pdf | \
while read THISLINE
do
  echo "${THISLINE}"
  firstWord=${THISLINE%%,*}
  restLine=${THISLINE##*,}
  newName="$(echo $firstWord | tr [:lower:] [:upper:] ) - ${restLine}"
  echo $newName
#  mv "${THISLINE}" "${newName}"
done

Uncomment the mv line if this is what you want.

Why not a simple

Code:

sed -nr 's/[^-]*/\U&/p'

@syg00: That's nice, but just one piece of the puzzle. How do you actually move the files (with special chars in it) using your command. Do give all the code please.

syg00 · 12-18-2009, 05:14 AM

Yeah, sorry; that was only meant to be the "guts" of the loop.

it changes every word to upper, at my side

Code:

$ ls *pdf | sed -nr 's/[^-]*/\U&/p'
GILBERT, MACHIAVELLI AND GUICCIARDINI.PDF

something like this (according to my memory..)

Code:

ls *pdf | sed -nr 's/[^-]*/mv \"&\" \"\U&\" /p' | bash

My bad - not concentrating; playing poker ...

. Can be done in sed, but not as clean as I was hoping

Code:

sed -nr -e 's/[^,]*/\U&/' -e 's/, / - /p'

MERDE!!! Here I was, thinking that when I came back nobody would have replied.
THANKS. THANKS. THANKS.

Just in case you are bored:
Among the pdf files, the format of half of them is like this:

Cooper (Justus Lipsius and the Revival of Stoicism in Late Sixteenth-Century Europe).pdf

I tried doing:

Code:

for file in *\).pdf
do
    front=${file%%(*}
    front=${front^^} #change case to upper
    back=${file#\(* }
    newname="$front $back"
		echo "FRONT=$front"
		echo "BACK=$back"
		echo "NEWNAME=$newname"
#     mv "$file" "$newname"

but I get:

COOPER Cooper (Justus Lipsius and the Revival of Stoicism in Late Sixteenth-Century Europe).pdf

The problem is in back

Hi,

In your original example there's always a , at the end of the first word, in the latest example there isn't (do post relevant examples

).

Slightly changing my suggestion will take care of the new example:

Code:

#!/bin/bash

ls *\).pdf | \
while read THISLINE
do
  echo "${THISLINE}"
  firstWord=${THISLINE%%(*}
  restLine=${THISLINE##*(}
  newName="$(echo $firstWord | tr [:lower:] [:upper:] ) - ${restLine}"
  echo $newName
#  mv "${THISLINE}" "${newName}"
done

(changes in bold).

Neither will do both (word, and word (). But the ls <regex> takes care of targeting the correct files.

Hope this helps.

remove the slash then, try again and see

musonio · 12-18-2009, 08:38 AM

THANKS once again.
That did it.

BTW: I had intentionally left this second part out so as not to bother you kind people. My idea was to get help on the basic procedure and adapt it to other cases. Unfortunately I couldn't when the () showed up.
