linux找不到这样的文件或目录，但是存在

Question

Then i trying to use this script

for line in `cat dirs.txt`; 
do 
find "$line" -type f \( -name '*good*' -o -exec grep -F "badbad" {} \; \) -exec echo {} \;; 
done

I get error on each existing dirs and match the find criteria

 find: /home/goods/ : No such file or directory find: /home/bads/ : No such file or directory find: /home/fill/ : No such file or directory 

But then i look manualy this dirs exist and i can read them all Why this happens?

Answer 1

Issue is that you have dos ( ^M ) line endings, in the file. Running dos2unix dirs.txt dirs.txt should solve the problem. Ideally, you also shouldn't use for line in $(cat ... , but something like

while IFS= read -r line; do
  find "$line" -type f \( -name '*good*' -o -exec grep -F "badbad" {} \; \) -exec echo {} \; 
done < dirs.txt

Answer 2

You must check in file for ^M$

You can do that with command cat dirs.txt -vET

Then you must trim them all with command cat dirs.txt|tr -d "\\r" >1.txt
