Top Forums UNIX for Beginners Questions & Answers Problem setting path to external hard drive as a variable Post 303030804 by RudiC on Saturday 16th of February 2019 04:18:40 AM

With bash, you have the "special treatment" of $'\xxx' strings during "parameter expansion". So nezabudka's proposal could be written like
Code:
echo ${var%$'\r'}


But I'm not sure that would remove your error message. Sure that directory exists? Doesn't have non-printing characters in its name? Is the external drive correctly mounted, and where?


Your entire script could be somewhat condensed:
Code:
#!/bin/bash                                             # have it run by bash, NOT sh, so bash new functionality is enabled
prev_dir=/Volumes/My\ Passport/test_reads_folder_a
new_dir=/Users/mylapple/desktop/test_reads_folder_b

for FN in $(sed 's/\r$//' targeted_files.txt)           # remove <CR> in the first place, running sed once in lieu of umpteen times
  do    cp $prev_dir/$FN $new_dir                       # use entire paths for the copy action
  done
