I have this script
#!/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:
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”
# 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' {} ;
