Hi guys,
And I thought it wasn’t a problem. Here’s my string
“/var/www/vhosts/mysite.com/httpdocs/public/file/mypic.jpg”
How do i take out all the text that comes before “mypic.jpg”?
Trickier than I first thought.
TIA,
Bing

File.basename(“/var/www/vhosts/mysite.com/httpdocs/public/file/mypic.jpg”)

Does File.basename require that the file exists on the local file
system?

If you have
filename = “/var/www/vhosts/mysite.com/httpdocs/public/file/mypic.jpg”
then
filename.gsub(/.*//,’’)
does what you asked, but
File.basename(filename)
works too.

No, it just understands how to parse things that look like filenames 
However, those filenames must use / characters.
You can also remove suffixes (e.g. remove the .jpg extension)

You could use the split method with a -1 array reference
eg.
“/var/www/vhosts/mysite.com/httpdocs/public/file/mypic.jpg”.split("/")[-1]
=> “mypic.jpg”

No, I used your filename in irb and I don’t have that file on my system.
The filename is just a string in the particular format of your OS.
If your OS uses a different format for filenames, then the parsing will
be different. Example: on Mac OS X, VMS filenames aren’t correctly
parsed:
File.basename(“NODE::DEVICE:[.DIR.DIR2]FILE.EXT;VERS”)
=> “NODE::DEVICE:[.DIR.DIR2]FILE.EXT;VERS”
On VMS Ruby (if there is such a beast) I’d get
FILE.EXT; VERS for this filename and
“/var/www/vhosts/mysite.com/httpdocs/public/file/mypic.jpg”
for yours.

I was initially using .gsub but couldn’t get it to work (this was before
I posted my question). I will try out gsub again, and the split method
and the one from Kevin…apparently there are more ways to skin a cat…
thanks so much for everyone’s help!
