Full Discussion: Script for linking files with paths in 2 text files
Top Forums Shell Programming and Scripting Script for linking files with paths in 2 text files Post 302891532 by Scrutinizer on Thursday 6th of March 2014 09:25:20 AM

@LeftoverStew, tt is a bit more complicated than that. A link in the same directory, means making the link to the file name only (without the path). Also, there are all sorts of error condition that might occur. Also since the match is made line for line by the content of the files, they need to be read at the same time.

For example:

Code:
complain() {
  printf "%s\n" "$*"
  continue
}

while read file && read link<&3
do
  # determine directories
  dir_file=${file%/*}
  dir_link=${link%/*}

  # determine name of new link
  new_link=${link%.*.*}_done.${link#*.}

  # determine name the local link should point to
  local_file=${file##*/}
  
  # complain if there are things wrong
  [ -e "$file" ]                || complain "file $file does not exist"
  [ "$dir_file" = "$dir_link" ] || complain "The directories of $file and $link are not the same, so a local symlink cannot be made"
  [ ! -e "$new_link" ]          || complain "An entry for $new_link already exists"

  # create the link
  ln -s "$local_file" "$new_link"
done < 1.txt 3<2.txt
