That looks like a linux platform.

If the thousand-odd files are in a single directory, and you like
visual interfaces, renaming them is very simple in a TUI-style
file manager like Midnight Commander (mc). You'd rename (called
Move) from *-1.svg to *.svg after selecting all the files with
the * keystroke.

If you prefer a CLI, then it's as simple as:

  $ cd directory-containing-files
  $ rename 's/-1\.svg$/.svg/' *.svg

except for the complication of which version of rename you have
installed on your system. I prefer the version that uses a Perl
expression, and it's set up as the default on my system for the
"rename" command, but can also be invoked as prename or file-rename.

Where files are scattered amongst directories, the CLI rename command
can be invoked from a find command, which searches directory trees for
suitable filenames to rename.

Cheers,
David.
