Sed taking too long 1

[mpramods]

I have number of files with '{' and '}' in it. I need to replace every '{' and '}' in this file to space.

I am using the following in a script:

sed 's/{/ /g;s/}/ /g' >temp
mv temp $1

It is taking too long since the files are very huge and they have many of these characters to be replaced.
Is there any other fast way to achieve this.

Thanks,
Pramod

There was a typo in what I wrote earlier.

The script I am using is:

sed 's/{/ /g;s/}/ /g' $1 >temp
mv temp $1


Is there any way I can make it more effecient

Hi

Try this, could be faster as it not work with regular expressions :

tr "{}" "  " < /input/file > /output/file

Great feherke. My sed was taking 3-4 hrs for each file. Your script does the same in 2 minutes.

Awesome............. You Rock.

Thanks,

Hi

By the way, [tt]sed[/tt] also has transliteration command, the [tt]y///[/tt]. This should also work faster then the [tt]s///[/tt] command.

sed 'y/{}/  /' /input/file > /output/file
