Bash query app information using the Launch Services
You can query app information using the Launch Services database to dump a list of all registered apps, then grep
for the one you want (in this case Google Chrome), for example:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister
-dump | grep -i "google chrome"
Gives me the output:
path: /Applications/Google Chrome.app/
executable: Contents/MacOS/Google Chrome
path: /Applications/Google Chrome.app/Contents/Versions/27.0.1453.116/Google Chrome Helper.app/
executable: Contents/MacOS/Google Chrome Helper
Bash Type Command
type: type [-afptP] name [name …]
For each name indicate how it would be interpreted if used as a command name
-t returns one of
alias, keyword, function, builtin, file, '' if name is an alias, shell
reserved word, shell function, shell builtin, disk file, or unfound
-p returns the name of the disk file that would be executed or nothing if
type -t NAME
would not return file
-P forces a path search for each name, even if it is an
alias, builtin, function returns
the name of the disk file that would be executed
-a returns all of the places that contain an executable named file
that includes
aliases, builtins, functions, if the
-p flag is not also used
-f suppresses shell function lookup
Example: get file path
command:
type -P node result:
/usr/local/bin/node
Example: get file type
command:
type -t node result:
file
command:
type -t source
result:
builtin
typeset:
typeset [-afFirtx] [-p] name[=value]

Symbolic Link
ln [options] (target file) [link name]
ln -sv /media/fileserver/anotherfile.ods /home/user/anotherfile.ods
s option creates a symbolic link, if omitted a hard link will be created.
ln will show what it's doing.
You could also
cd to target's directory first:
cd /media/fileserver ln -sv anotherfile.ods /home/user/anotherfile.ods
Or
cd to destination directory:
cd /home/user/ ln -sv /media/fileserver/anotherfile.ods
If you omit the link name, target's name is used. The above command creates a link to
/media/fileserver/anotherfile.ods in
/home/user/anotherfile.ods
