hai anchal
when i am executing this shell script it is saying that
mv: target `./*.txt' is not a directory
what is the problem
i am not getting
actually in my file i have to replace ^M with spaces.
sp what change i have to make over here
plz replay me ASAP
THANK U

That error message doesn't make sense. What does find $path -name "*.txt" -print | less print for you (and did you remember to set path to something useful)?

The replacement is probably better done with tr -- if yours doesn't understand '\015' then try typing a real control-M there (might need to type ctrl-V ctrl-M to actually get one).

Code:

find $path -name "*.txt" -print" |
while read file; do
  tr '\015' ' ' <"$file" >"$file".tmp && mv "$file".tmp "$file"
done

hai
i have done like this
find $suvendu -name "*.txt" -print" |
while read file; do
tr '^M' ' ' <"$file" >"$file".tmp && mv "$file".tmp "$file"
done

but here again some problem is coming
like-
shell1.sh: line 3: unexpected EOF while looking for matching `"'
shell1.sh: line 5: syntax error: unexpected end of file
so whats the problem can u tell me
plz tell me ASAP

remove incomplete " after -print.

but it is not working yarr
i dont know why
i have done like this
for file in `find . -name "*.txt" -print`
do
sed "s/^M//g" $file > temp; mv temp $file;
done
~
it is executing succesfully
but it is not changing anything
inside the .txt file
so plz give me the solution ASAP
