If the shell noclobber environment variable is set, you will not be able to overwrite a file's content by redirecting some output to it. Code: # echo "2nd Overwritten content">tmp.file bash: tmp.file: cannot overwrite existing file First option would be to disable the noclobber variable: Code: # set +o noclobber; set -o | grep nocl noclobber off The second option is to use the pipe (|)right after the redirection sign: Code: # echo "2nd Overwritten content" >| tmp.file
# cat tmp.file 2nd Overwritten content |
