Generate command line equivalent?

[fncll]

When I convert a particular .mobi file to .epub using the Calibre GUI on my main computer, it works fine. When I try to convert the same file using the command line on a VPS server, it fails near the end saying "killed."

Can I generate a command-line from the calibre GUI so I can figure out what option(s) are causing the failure on my remote computer? Or do I need to use the verbose output and compare all the options one-by-one?

I have a .mobi file that converts fine using Calibre GUI on my main computer (OS X) but fails on the command line on a Linux (CentOS) VPS. Here's what I get (as you can see, I've been testing some options...without specifying options the conversion stalls, forever, at removing "fake margins"):

Spoiler:

$ ../calibre-bin/calibre/ebook-convert 0877798222-dt.mobi 0877798222-dt.epub --disable-unwrap-lines --disable-remove-fake-margins --dont-split-on-page-breaks --flow-size=10000 --disable-dehyphenate -v -v -v

Killed

I posted a different thread about how I might figure out the difference in the options that the GUI version is using vs the command line, but trying to compare one by one is painful...so, any ideas what to try?

Copy paste the debug output from the GUI and command line into two separate files and use a diff program to see the differences.

Although if I had to guess, I'd guess your VPS is killing the process because it runs out of memory.
