How to check if filenames are lowers case.

gqchynaboy · 02-05-2010, 10:07 PM

What would be the best way to verify files in a folder are all lower case and if a file is not lower case, output the filename to the screen.

>ls | grep \[~A-Z\]

Happy Penguins!

edit:
You also need to be specific, all lower case and not lower case are not exclusive. There are many occasions (not lower case) AND (not upper case).

Hey -

Well I have a image folder and in that folder are a bunch of *.gif images.

I want to verify filenames are lowercase, for example 'main.gif' and not 'Main.gif' / 'MAIN.gif' / 'maIN.gof' / etc.

But what you gave me seems to give help too =]
Thanks for your help

How would I do it for a .HTML file itself now? For example the HTML contains img src="images/lockup.gif" I want to verify all other images are 'some_pretty_pic.gif' and not 'Some_Pretty_Pic.gif' and if it does contain uppercase, output it to the screeen.

Something like

Code:

grep -E 'img src=".*[A-Z].*\.[Gg][Ii][Ff]"' *html

should work.

Cheers,
Tink

Hya,

Be careful anything like _123.gif

Do you what them or not?

Happy Penguins!

P.S. My previous post was incorrect. Should have been 'exclusive or" instead of "exclusive"

Having _1234.gif is okay to have in a fielname and
grep -E 'img src=".*[A-Z].*\.[Gg][Ii][Ff]"' *html
seemed to do it's job. Now only thing is that it's hard to read, I would like to only see maybe 'images/02_140_A9_Reg_EM_PRO_r2_08.gif' and not the whole line of HTML code. I assume I need to use the sed command and some how parse it out?

Code:

valign="top" bgcolor="#ffffff" ><img src="images/02_140_A9_Reg_EM_PRO_r2_08.gif" width="35" height="69" border="0" alt=""></td>

Easy enough, no need for sed:

Code:

grep -Eo 'img src=".*[A-Z].*\.[Gg][Ii][Ff]"' *html

In action:

Code:

echo 'valign="top" bgcolor="#ffffff" ><img src="images/02_140_A9_Reg_EM_PRO_r2_08.gif" width="35" height="69" border="0" alt=""></td>'| grep -Eo 'img src=".*[A-Z].*\.[Gg][Ii][Ff]"'
img src="images/02_140_A9_Reg_EM_PRO_r2_08.gif"

Cheers,
Tink

Wow that was too easy, thanked!!

I actually just noticed that sometimes I need to upload the images to a FTP server and when this happens their are uppercase letters in the file path, so it's spitting everything out. =[

Code:

grep -Eo 'img src=".*[A-Z].*\.[Gg][Ii][Ff]"' *html

outputs:

img src="http://someFTPserver/Proj/Games/Creative/Mass_Effect_2/Code/R3/images/Spacer.gif"

I kept trying to play with grep so it only spits out 'Spacer.gif' or 'images/Spacer.gif' but not successful =.

Add the basename cmd http://linux.die.net/man/1/basename

Marginally more involved ;}

Code:

egrep -o 'img src=".*/[^/.]*[A-Z][^/.]*\.[Gg][Ii][Ff]"'

And in action:

Code:

$ echo 'img src="http://someFTPserver/Proj/Games/Creative/Mass_Effect_2/Code/R3/images/spAacer.gif"' | egrep -o 'img src=".*/[^/.]*[A-Z][^/.]*\.[Gg][Ii][Ff]"'
img 
src="http://someFTPserver/Proj/Games/Creative/Mass_Effect_2/Code/R3/images/spAacer.gif"
$
$ echo 'img src="http://someFTPserver/Proj/Games/Creative/Mass_Effect_2/Code/R3/images/spacer.gif"' | egrep -o 'img src=".*/[^/.]*[A-Z][^/.]*\.[Gg][Ii][Ff]"'
