From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Regular expressions in Double Commander to skip incompatible symbols when copying (feddit.nl)

Hi all,

I've been breaking my head on this for the past while and I figured I'd ask the hive mind here.

I'm using Double Commander as my file browser of choice, and I'm copying some files to an SD card that goes into an mp3 player running Rockbox, which only accepts FAT32 file systems.

I've tried to get all the filenames as compatible with FAT32 as possible, but here and there there's still some file names that contain symbols incompatible with FAT32 ( , \ , / , : , * , ? , " , < , > , | .)

Now, Double Commander allows to use file templates for copying files, which includes the option for a file mask using regex. I figured I ought to be able to use this to skip files using these characters. Looking at regex syntax and googling for something similar to have already been done (I found this Stackexchange question) I came up with this regular expression:

[^\\/:*?\"<>|]

Double commander then spits out the following error, though:

Unhandled exception: ERegExpr: TRegExpr compile: quantifier ?+*{ follows nothing (pos 1)

Any ideas on what I'm doing wrong? Regex is kind of foreign to me, so I'm guessing I'm doing something fundamentally wrong that should be easy to solve for someone who knows what they're doing.
