Shell脚本无法CD进入包含空格的目录

Question

I have a shell script that loops into each directory and finding a file. The problem I have is shell script is unable into cd to a directory that contains space. Here is example script.

First method:

for dir in "$(find /usr/tom/public/junk -maxdepth 3 -type f -name testfile)"; do
        cd "$(dirname "$dir")"
        printf "%-54s" $(basename $PWD)
       done 

second method:

find "/usr/tom/public/junk" -maxdepth 3 -type f -name testfile -print |
  while IFS= read -r dir
  do
    cd "$(dirname "$dir")"
    printf "%-54s" $(basename $PWD)
    done 

Error : No such file or directory ( because some directories contains spaces)

my requirement is -> When a "test" file is found in a directory then it has to delete that directory.

I am running this script on ubuntu.And the weird part is, this piece of code working in my Mac but not on ubuntu server. I have no idea why it is not working on ubuntu. Please help me.

Answer 1

The problem with spaces in directorynames can be circumventing by using read to process the output from find . There is an very thorough explanation for that in this answer . For your situation, something like this would work:

find /usr/tom/public/junk 3 -type f -name testfile | while read dir; do
    cd "$(dirname $dir)"
done

Answer 2

Use double quotes to the directory names.

mahendra@test-Ubuntu:~$ cd /test
mahendra@test-Ubuntu:-Ubuntu:/opt$ cd "new test"

As the folder you want to connect has spaces in the name, you must surround the name with quotes in order for the Shell to read it correctly (as one name).

now you need to check how you can pass "" to directories in the shell script.

another way is you can use the backslash

cd test\ Text\ 2/

the backslash followed by a space explicitly denotes a space.

suggestion: do not create a directory with space in Linux.
