adb shell命令-cd：没有这样的文件或目录

Question

I use an android 4.0 system on my device, when I use adb shell log in and want to go to the /cache directory with using cd cache, but it just show

/system/bin/sh: cd: /cache - No such file or directory

Why? I really see the cache use ls command, it shows like

lrwxrwxrwx root root 2012-03-12 10:22 cache -> /data/cache"

Cd to other directory is ok. Has anybody can help me?

Answer 1

Instead of

cd /cache

do

cd /data/cache

or

If you type ls and you see cache, you should type cd cache because cd /cache is a directory just under the root /

Answer 2

/cache is a symbolic link to a non-existent directory. cd /cache is the same as cd /data/cache . if /data/cache does not exist (which looks to be your problem) you'd get the "No such..." error.

Additionally, if you do ls -L /cache you'd get the same "No such..." error; that's because the -L option tries to list the target of the link (which does not exist, in this case) instead of the link.

Finally:

ln -s  this_directory_almost_certainly_does_not_exist   not_sure_if_this_exists
test -f not_sure_if_this_exists || echo 'Nope, it does not exist'
