[Old Thread] Calibre Command line and .bat file

I'm using Win XP and having problems executing multiple command lines in a .bat file. Each line can be copied and executed individually in the command prompt, but when I collect them into a single file, the batch dies after successfully completing the first conversion. The paths are mapped correctly, otherwise it wouldn’t complete the first command.

The command line looks like this:

ebook-convert "Z:\directory\file1.pdb" "Y:\directory\file1.epub" --no-default-epub-cover --line-height=16 --base-font-size=12 --margin-top=15 --margin-left=15 --margin-right=15 --margin-bottom=10 --remove-paragraph-spacing --use-auto-toc
ebook-convert "Z:\ directory\file2.pdb" "Y:\ directory\file1.epub" --no-default-epub-cover --line-height=16 --base-font-size=12 --margin-top=15 --margin-left=15 --margin-right=15 --margin-bottom=10 --remove-paragraph-spacing --use-auto-toc

etc.

I believe this is a known issue. Not sure what makes it happen though.

It's a known issue. A workaround I found is to precede each line with "start" in your batch file. That spawns a separate command com for each line, and each dies with its line, but only after completion of the line.

My guess would be you are not running ebook-convert directly but through a BAT file. That would result in the behavior you describe.

Even if it is not the case, the fix that would have worked with BAT files will likely work for your case: Just prefix your calls to ebook-convert with either call or cmd /c. Unlike the start fix, this will NOT start a new console window for each ebook-convert, and it will run te commands sequentially rather than all at once.

I tried both call and cmd /c when trying to work around problems with calibredb and batch files. It's true they don't spawn another cmd session, but they also didn't work. Calibredb crashed the first session every time, so the batch would never complete. I don't know if ebook-convert is different, but, at least for calibredb running in a batch file, you need to use start, or the Powershell workaround.

If your batch needs sequential operation, then you need to be trickier or use Powershell.

Just found this and thought I would add a comment.

One of the issues you encounter with using "start" is redirecting output to a text file
start "" /WAIT calibredb.exe .... >out.txt

This does not work as the output redirection doesn't get passed.
The normal way to fix this is to escape the > with ^>

start "" /WAIT calibredb.exe .... ^>out.txt

But for some reason this does not work with calibre, the process works but calibre doesn't seem to understand the command line that was passed

This next solution works, but I have no idea why :-(, putting additional ^'s breaks it

start "" /WAIT cmd.exe /c ""calibredb.exe^" .... ^>tmp1.txt"

For a solution I can understand, this works ...

echo @%calibredb% ....>tmp.cmd
start "Calibre" /WAIT /MIN cmd.exe /c tmp.cmd ^>tmp.txt

Hope this helps someone :-)

ooo, this trick seems to work also

start "Calibre" /WAIT /MIN cmd /c (calibredb.exe ... )^>tmp.txt

quotes seem to work fine with the (), for example:-

start "Calibre" /WAIT /MIN cmd /c ("c:\Program Files\Calibre2\calibredb.exe" list --separator , -w 255 -f authors,cover -s "title:Zero Game")^>tmp.txt

enjoy!

Cool

First, there is a limit of 127 characters to any MS-DOS command line; more then 127 characters and MS-DOS truncates the line without a warning. This is not a Calibre bug, but intrinsic to MS-DOS, and Microsoft has declined changing it for over 20 years. See
http://support.microsoft.com/kb/69563
(IBM field engineers are trained to say “that isn’t a bug, that’s part of a feature for our other customers” when they are backed into a corner.)
I have launched
ebook-meta ThisBook.epub --to-opf file.opf
Then edited the .opf file, for
ebook-meta ThisBook.epub --from-opf file.opf --other-meta
but if there is an equivalent way of loading the ebook-convert non - meta data, I haven’t found it.
A feature of Windows is that it tries to launch all the Windows programs it can find in a .BAT file at one time. Helpful if you’re trying to get 2 spreadsheets and 3 documents going at once; but irritating for sequential processing. What I have found myself doing in a .bat is:
copy "Eusebeus Church History.htm" in.htm
del *.epub
ebook-convert in.htm w.epub --output-profile nook --level1-toc //h:h2 --level2-toc //h:h4 --max-toc-links 0 --chapter /
This is barely under the length limit, but I get all the TOC stuff on one line. There is no space remaining on the line for a pause technique. Then I hand launch a second .bat
ebook-convert w.epub o.epub --output-profile nook --smarten-punctuation --change-justification left --pretty-print
in a second .bat file, this does all the “cosmetic treatment.”
Then a third batch file I hand launch is
ebook-meta o.epub --cover Eu.jpg --author-sort "Eusebius of Caesarea"
which adds the meta data that it can’t find in the HTML.
Oh yeah; one more batch file. Number four.
start "" /w "calibredb.exe" add -d o.epub
start "" /w "ebook-viewer.exe" o.epub
Lets me see the results, and places it in the DB.
If you name the batch file sequentially, conv1.bat conv2.bat conv3.bat conv4.bat; well I’ve got decades of COBOL experience, so I’m brain damaged to the point where it seems acceptable. For the sake of the rest of humanity, and to bypass two MS-DOS/Windows bugs at once, it would be nice if there was one additional option:
---------------------------
ebook-convert in.htm o.epub --command-line misccmds.txt
---------------------------
where misccmds.txt would contain all the familiar calibre line commands; either all on one line, or preferably, it being possible to spread out the line commands with their parameters over more then one line. (.txt extension preferable so it would open automatically with Notepad/VIM/etc.).
Thank you for your attention to this matter; and the excelent product. Usually doing everything through the GUI interface is good enough for me, and I'm done in two minutes, but once in a while . . .
P.S. I have done enough stuff in Linux to be able to see how it would be helpful to combine different misccmds.txt files with cp, as with MS-DOS copy, since you might want to combine preferred formatting, (second ebook-convert above) with book specific meta-data.

You rather than giving yourself a hernia jumping through microsoft hoops, why dont you just use a decent script language instead of BAT. You can even do it with calibre itself for example:

Create a .py file called myscript.py
Code:
import subprocess, sys

# Command line arguments ar in sys.argv
print 'Command line arguments', sys.argv

subprocess.check_call(['ebook-convert', sys.argv[1], sys.argv[2]])
subprocess.check_call(['ebook-viewer', sys.argv[2]])
Now run this script with

Code:
calibre-debug -e myscript.py input_file.epub output_file.epub
This will run ebook-convert for you and open the result in the viewer.

I'm sure you can figure out the rest.

Once more, please.

This
subprocess.check_call(['ebook-convert', sys.argv[1], sys.argv[2], --cover eu.jpg])
blows up,
this
subprocess.check_call(['ebook-convert', sys.argv[1], sys.argv[2], "--cover eu.jpg"])
died
this
Ptotal = " --cover eu.jpg "
subprocess.check_call(['ebook-convert', sys.argv[1], sys.argv[2], Ptotal])
produced the default cover,
this
subprocess.check_call(['ebook-convert', sys.argv[1], sys.argv[2] + " --cover eu.jpg"])
died, and I was laughing before I tried it;
subprocess.check_call(['ebook-convert', sys.argv[1], sys.argv[2], """ --cover eu.jpg"""])
generated the default cover.
OK, I give, what does replacing the cover look like?

Thanks!


Thank YOU! This works!

'--level1-toc ', '//h:h2 ', \

'--max-toc-links ', '0 ', \

'--preserve-cover-aspect-ratio ', \

subprocess.check_call(['ebook-convert', sys.argv[1], sys.argv[2], Ptotal])


(Except for the 'rating' and 'author-sort'; I can work around those)
I love Calibre!

Use code tags. In the advanced edit dialog, it's the hash sign ('#').
