How to supress the file name when we check for disk space ?

I used this command :

du -ks /home/dir1/dir2/file.csv

it returns

13     /home/dir1/dir2/file.csv

Please explain the options too

You may use this:

du <filename> | awk '{print $1}'

Thank you. I am wondering du command executing in the command line.
But when i gave the same command in .sh file. it is giving

du: cannot access /user/dir1/dir2/file1\r : No such file or directory

i wonder how "\r" comes at the end. Please provide a solution

Please post the output of cat -A <script_file> . This should be the common carriage return problem faced when porting files created on windows to unix.

du -sk /user/dir1/dir2/file1  -> its working
path="/user/dir1/dir2/file1"
du -sk $path -> working
path=`head -1 export1.tsv | awk '{ print $5 }'`
      du -sk $path  - Not working 
 
cat export.tsv

hi,
you can remove the ctrl+M character by running the following command on file

dos2unix  export.tsv export.tsv

thanks,
venkat

Moderator comment: Syntax should be:

dos2unix export.tsv > export_new.tsv
# Or if you have the command under the new name
dos2ux export.tsv > export_new.tsv

@arukuku: There're lots of posts on how to remove the end of line control character. Check this post : www.unix.com/shell-programming-scripting/175130-unix-problem-new-line-character.html

And, try this:

path=`head -1 export1.tsv | awk '{ print $5 }' | tr -d '"'`
du -sk $path

Combining all the above ideas: Getting rid if the MSDOS carriage-return character, removing the double quotes, and outputting only the total from "du".

path=`head -1 export.tsv | awk '{print $5}' | tr -d '\r"'`
du -sk ${path} | awk '{print $1}'
