For those who do not know :
A simple but a crude way to check for a required .tcz for external linux command in TCL , open a concerned repository page in a browser . For example :
http://distro.ibiblio.org/tinycorelinux/3.x/tcz/index_nojs.html Use find on page feature , type the name of external command. Ex: unclutter , and search.
The row with unclutter will be highlighted and in the right side the required .tcz will be found.
There are other ways, to know abt such things. For Ex: In Debian and its derivatives :
To know dependencies of a particular package.To list what a package use :
apt-cache depends vim
There are other commands to achieve the same task depending on linux distro , pl check which one works for you :
pactree vim
tree vim
To retrieve one or more public keys from a public keyserver , use :
whatis ssh-import-id
There are other internal comands as well like : which etc. But that is a diff topic.
