在当前目录中执行Shell脚本

Question

I am writing a shell script to list the five folders consuming the most space. Here is what I have:

$ du -m --max-depth 1 | sort -rn 5

This works fine, but how do get this code to check the directory that it is called from?

Answer 1

Check whether this answers your question:

$dir=`pwd`

if [ $dir = "some_directory_you_are_expecting" ]
then
    du -m --max-depth 1 | sort -rn 5
else
    do_some_other_thing
fi

Answer 2

You are giving "5" as the file to be sorted, but you want to sort the output from du. Perhaps your sort is different. Mine is from http://www.gnu.org/software/coreutils/

here:

$ echo 'du -sm * | sort -rn | head -n5 ' > ~/bin/top5.sh 
raptor: ~
$ chmod 755 ~/bin/top5.sh
raptor: ~
$ top
top      top5.sh  
raptor: ~
$ top5.sh 
606     src
532     svn
407     tmp
349     images
45      workspace
raptor: ~
$ cd /usr/
raptor: /usr
$ top5.sh
