sed remove all occurrences in a string
 
I have:

Code:
C:\u002Cdata\u002CDocuments
If I used:

Code:
sed 's/u0052//'
It only removes the first occurrence. How can I remove all occurrence in the line?

Thanks & Regards

Tack a g at the end of the expression
Code:
sed 's/u002C//g'


Cheers,
Tink

Thanks.

Just a bit more on what I am doing. From the command line it works fine:

Code:
[me@host scripts]$ FOLDER=$(echo "C:\u002Cdata\u002CMy Files" | sed 's/C:\\/\//' | sed 's/u005C//g' | tr '\' '/' | sed 's/ /\\ /')
[me@host scripts]$ echo $FOLDER
/u002Cdata/u002CMy\ Files
But when I put this in a my script it errors out.

Code:
FPATH="C:\u002Cdata\u002CMy Files"
FOLDER=$(echo "$FPATH" | sed 's/C:\\/\//' | sed 's/u005C//g' | tr '\' '/' | sed 's/ /\\ /')
I think its something funny going on with the space in between My Files but not sure how to handle this.

Thanks & Regards

And what is the error it errors out with?

hattori.hanzo 11-21-2010 07:47 PM
It came with

Code:
sed: -e expression #1, char 11: unknown option to `s'
So I put in back ticks and now the command works fine

Code:
FPATH="C:\u002Cdata\u002CMy Files"
FOLDER=$(`echo "$FPATH" | sed 's/C:\\/\//' | sed 's/u002C//g' | tr '\' '/' | sed 's/ /\\ /'`)
But the result $FOLDER is not what I was expecting:

Code:
C:/data/My:
I am looking for this:

Code:
/data/My\ Files
UPDATE: Solved

Code:
FPATH="C:\u002Cdata\u002CMy Files"
FOLDER=$(echo "$FPATH" |  sed 's/u005C//g' | tr '\' '/' | sed 's/C://')
find /mnt/win"$FPATH"
Thanks Tinkster for the input.

Thanks & Regards

May I also suggest that when dealing with the slash (/) that you use an alternate symbol for search and replace in sed to make it clearer.
eg
Code:
FOLDER=$(echo "$FPATH" |  sed 's@C:\\@/@')
Here is a sed alternative for the whole line:
Code:
FOLDER=$(echo "$FPATH" | sed -r -e 's@(C:|u002C)@@g' -e 's@\\@/@g'
