hai all i have some doubts in linux commands can any one tell me how to make a directory inside a directory using a single command(like a tree) eg: a/b/c/d/ where a, b,c ..are directories.. and how to list the files and folders without the color schemes? plz reply soon regards faheem

1. Making directories with subdirectories (note, the $ is the prompt. DON'T TYPE IT IN!): $ mkdir a a/b a/b/c This will create directory a, directory b under a, and directory c under a/b. 2. Listing files without color schemes. This happens because the 'ls' command is an alias for the real 'ls' command. Do this: $ unalias ls Now, the 'ls' command will not display the colors. I agree, it is sometimes uninformative, or distracting. However, it does help to find soft links that have lost their target (blinking red). I usually prefer the command: ls -aFC which will show directories with a terminating / and hidden files that start with a dot.

you can create directories inside directories using "mkdir -p /a/b/c/d", this will try to create the d directory, and if it doesn't find its parent directories it will create them (i.e if you don't already have a/b/c it will create them for you.).

Thanks a lot to all

Indeed. I learned all the command-line stuff way back in Unix's early middle-ages (my first Unix box was back in the early 80's), and as I recall I don't think there was a -p option to mkdir. Maybe I should update my knowledge base? :-)
