Shell Programming and Scripting

if u are not using any shell variable inside the sed syntex.. thn use single quotes instead of double with in the sed. hope it 'll work

sed 's/^M//g' $file

for file in `find . -name "*.txt" -print`
do
sed "s/suvendu/anil /g" $file > temp; mv temp $file;
done
~

when i am replacing suvendu with anil it is working
but when i want replace it from ^M to ' ' it is not working
so i dcontknow whats the problem in this

for file in `find . -name "*.txt" -print`
do
sed 's/^M// g' $file > temp; mv temp $file;
done
~
i have done like this
but again it is not working yarr

try this

for file in `find . -name "*.txt" -print`
do
sed 's/\^M// g' $file > temp; mv temp $file;
done

it 'll work

It's not clear whether the files and/or your command lines contain the two characters "^" and "M" or real actual carriage returns (ASCII 13). My uninformed guess is you are mixing these up.

It's also possible that your sed cannot cope with literal carriage returns. Try tr again in that case. If you cannot get tr to accept either '\015' (that's octal for 13) or a literal ctrl-M, you will need some heavier workaround.

Actually here's one.

Code:

find . -name '*.txt' -print | xargs -n 1 perl -i -pe 'y/\015/ /'
