Question about creating files, and upper and lower case letters


What is the programme that writes files on to the hard drive? and then writes the filename to creates the inodes (?)



To give an example, say Im downloading a file called 'Match Of The Day.avi. Is there an option to the programme that is handling the writing of the file to the hard drive to write all the letters in the filename to lower-case?

Your first question ultimately refers to system calls and filesystem operations. Not going to speak to that, when I think your real (much simpler) question is:

It depends on the program you're using to download the file. If you're using wget(1), for instance, there is an -O (that's a capital "o") option that can be used like so:

Code:
$ wget -O good-sneaky-name.html 'http://google.com/index.html'

You can name a downloaded file anything you want.

@clifford227: At second read, I think you're actually asking whether you can keep the name, but convert it to lower case. I can only think of contrived scripting methods for doing so. Don't know of any tidy program option.

wget(1)'s --restrict-file-names may be promising, but I've never tested it.

First let me apologise for this late reply.

I dont have my desktop system up and running yet (Im waiting for Slack 14), and in the meantime I am having to borrow a laptop from someone else.

Unfortunatley, almost immediately after creating this thread, I had to give the laptop back, and I am only now able to reply.

Yes, thats correct.

The reason I wanted to do that was because I was having problems with the 'find' command, which has been driving me up the wall.

I have now stumbled upon a partial solution, the ls and grep commands which I then use in an alias:

Code:
alias search='ls | grep -i'
When given a search word in either upper or lower case, the alias returns both upper and lower case matches.

If you use find with the -iname option instead of the -name option you have the same effect: a case-insensitive search.

I did try the -iname option, but I was getting some strange results.

(Although it is possible that I wasnt using the find command properly. I had a hard time following the man page.)

If I remember, if there was only one file with a name containing a search word, find would find it and print it to the screen, but if there were two files that contained the search word, find wouldnt list either, or it would only find a case-sensitive match (I cant quite remember exactly, but find wasnt giving me the results I expected).

find with case IN-sensitive search
Code:
find /somedir -iname '*.dat' -print
It really does work as TobiSGD said

Chris,

I'll take another look at find tomorrow, and see if I can reproduce the problem.

The 'iname' option is not always available; depends on the implementation of 'find' in the distro. I ran into that problem last night while using DSL. And the error message in this case left a lot to be desired

That is because DSL uses the find program that is inbuilt to Busybox, for space reasons. Most Busybox versions of commands come with a reduced feature set, otherwise they would take the same space as the GNU and BSD versions.
