bash - For loop using find lacks doesn't properly handle directory names having white space character -

OK I'm really stuck on this.

I have dirs.txt that is as follows:

  / var / tmp / old files.txt / var / tmp / old backups.bak  < / Pre> 
 The dirs.txt file is generated by the script 
 
 When I want to use dirs.txt in a loop for: 
 
  ` Dirs.txt` for dir; Command throws: ls: can not use / var / tmp / old: no such file or directory  
 I want  
 Full filenames can be used by LS-L'Aid But it does try LS-L / var / tmp / old /  
 how can I fix it with a loop?   
 
 
  cat dirs.txt | While reading DIR; When you use a bactic operator, the output is divided into tokens on the character of each white spot. I ls -al "$ dir" done  
 
 
 
 The second On the side,  read , reads one line instead of one word at a time. So the solution, which looks odd, is in the loop in the loop so that it can be read by line. 
 
 
 
 You need the quote  "$ Dir"  in the  ls  command to the full filename, the white location and all If you do not do this, then  ls  two filenames,  / var / tmp / old  and  files.txt < / Code>. 
 
 
 
 Maybe I'm going to honor you. You can  cat : 
 
  It can make it even easier by eliminating what LS-L "$ dir" did & lt; Dirs.txt  
 
 This works because < Strong> Whole   while the  loop acts like a large command, so you can also use file redirection in the  cat  like a pipe. 
 
 
 Taking it even further ... 
 
 how  dirs.txt  is generated, you can get rid of it completely You can do everything in one command and if it is just a temporary file, you can reduce it by piping and make  dirs.txt  in . Whereas  loop directly, leaving a temporary file. For example, replace 
 
  / var -name '* old *' & gt; Dirs.txt while reading dir; Did LS-L "$ dir" & lt; Dirs.txt  
 
 with 
 
  find / var -name '* old *' | While reading DIR;  lin-l "$ dir" done  
 
 excuse  find  whatever order you make to create a file list. 
 
 And in fact, if you are actually using  search  then you might find a large  order  in the order without any end Or can do anything! For example, with  search  and  while  can be done with a single  search  command: 
 
  Find / var-name '* Old *' -exec ls -al {} \;  
 
  search  is actually a flexible command that can detect files that match all kinds of complex criteria, and those files are called command line logic You can pass by using the other commands as  -exec  option when you use  -exec  then  {}  each file name Gets replaced with.
