[SOLVED] How to start file in different directory

alexa-lol · 05-19-2011, 08:15 AM

Hej

I am having troubles starting superPI benchmark test on Linux. I have it in a file named 'super pi' so ./super_pi doesn't work. I can't figure it out how to do it.

In cmd(Win) I would do it like this
cd C:/super pi/
super_pi
If the file would be located in C:/super pi/

The problem is I somehow can't tell the path to the file.

Cheers

"doesn't " work is not a sufficient description of this error. Please post the exact error-message.

Aren't you using linux with graphical environment and file manager with gui? It would be way easier. If you want from terminal steps are similar to Windows. Type "cd path" then run with "sh filename" but are you sure that the file you want execute is linux compatible or you are trying run .exe?

hej

thanks..
Well I could not change the directory. The problem is super pi is are 2 words. I renamed it to super and now it works. But how would I move to the directory named super pi or any other with space in the name?

I also get Segmentation fault. I will update all of the drivers and try again.

A few ways:

1. Use tab completion. Start typing the name of the directory, hit the TAB key and it should automatically complete (assuming the part you've typed is unique)

2. Escape the spaces with "\", e.g. "cd dir\ with\ spaces".

3. Put the directory name in double quotes.

Also
4.Use * to give anything in that place. For example "cd super*" will pick folder starting with super(case matters!) in name. If you have only one called that way there will be no problem otherwise it may not work and you may need use "cd super*pi" which will take starting super and ending pi.

On the super pi file you need to use thusly:

# /<your path>/super\ pi/

On tab completion there is also a double tab '<tab><tab>'
where you get a list with only typing the first two letters of the file
if there are similar file names.

You can make an .sh file (see advanced bash) for your convenience.
Or cover-copy/paste a file.
Or an alias.
Also make complete readme notes on what you did and when.

What if you have two folders: "super pi" and "supergfdgghhpi"? It's unlikely, but there will always be the possibility of conflicts when using globs for such a purpose.

By the way, if you use Linux, it's a good idea to avoid putting spaces in filenames since they are a pain to work with in the command line. Use underscores ("_") or dashes ("-") instead.

thank you all for replying

I used \ but the thing just did not want to work. I have resolved my issues now

What do you mean by "did not work"?

Remember, there has to be a space after the "\". What the backslash does is it tells bash to interpret the following character literally.
