linux - Check if directory exists not working -

i have textfile (qrs.txt) contains dir names (one per line) , on server in same directory script have folders corresponding names text file.

this script:

#!/bin/bash  while read p;   if [ ! -d "$p" ];             echo "error $p" >> log.txt     else         echo "good" >> log.txt     fi done < qrs.txt 

qrs.txt:

1992300000183805 1992300001176204 1992300002145500 1992300003104507 1992300004104902 1992300005133703 1992300006117802 1992300007144501 1992300008172803 1992300009189005 1992300010146307 1992300011151700 1992300012190007 1992300013126802 1992300014111508 1992300015193908 

when if statement inside loop returns error incorrect because can see folders exist. when take out of loop , check 1, works fine... when echo $p on same line error, can see file name checking indeed correct.

what missing here..?

resolved!

my qrs.txt in [dos] format once converted unix format using ":set ff=unix" script worked charm!

your script works fine.

i copied script local machine. when put blh blah in qrs.txt file, got error each time ran script. ran 4 times. changed blh blah valid path , received good.

the directory 1992300000183805 instance, may not valid path. need qualified path name! example, /home/user/1992300000183805.

error blh blah error blh blah good 

edit

looking @ @chepner comments, recreated problem:

open qrs.txt file in vi or vim. should see ^m @ end of lines. remove ^m characters @ end of lines in vi, use:

:%s/^m//g 

this should fix problem. if not, in vim type this:

:set ff=unix

save file.

re-open qrs.txt in vim, run regex above again, or manually delete ^m.

or can use perl:

perl -pi -e "s/\r/\n/g;" <file>
