I have this script
JavaScript
x
#!/bin/sh
for i in `ls -R`
do
echo "Changing $i"
fromdos $i
done
I want to remove “^M” charcaters from many files which are in more subdirectories. I got this:
JavaScript
fromdos: Unable to access file
Is there somethig i’m missing?
Thanks in advance.

I guess you don’t need a for loop.
Here is a quick panorama of solutions for files with extension “.ext” (such commands shall be somehow restrictive)
note : ^M is obtained with CTRL-V” + “CTRL-M”
JavaScript
# PORTABLE SOLUTION
find /home -type f -name "*.ext" -exec sed -i -e 's/^M$//' {} ;
# GNU-sed
find /home -type f -name "*.ext" -exec sed -i -e "s/x0D$//g" {} ;
# SED with more recent nux
find /home -type f -name "*.ext" -exec sed -i -e "s/r$//g" {} ;
# DOS2UNIX
find /home -type f -name "*.ext" -print0 | while read -r -d "$(printf "00")" -r path; do dos2unix $path $path"_new"; done
# AWK
find /home -type f -name "*.ext" -print0 | while read -r -d "$(printf "00")" -r path; do awk '{ sub("r$", ""); print }' $path > $path"_new"; done
# TR
find /home -type f -name "*.ext" -print0 | while read -r -d "$(printf "00")" -r path; do cat $path | tr -d 'r' > $path"_new"; done
# PERL
find /home -type f -name "*.ext" -exec perl -pi -e 's/r//g' {} ;
