How to view CHM files in Ubuntu?
Install the xChm Viewer for viewing CHM files:
sudo apt-get install xchm
chmsee is no longer available in Ubuntu, as it is no longer being maintained. Here is the announcement on the project site:
ChmSee is not being developed anymore.
I haven't read CHM documents more than a year, new and update IT books are pdfs or epubs, so it's right time to end this chm viewer.
sudo apt-get install chmsee
The main advantage of kchmviewer is the best support for non-English languages. Unlike other viewers, kchmviewer in most cases is able to correctly detect the chm file encoding and show it. It correctly shows the index and table of context in Russian, Spanish, Romanian, Korean, Chinese and Arabic help files, and with new search engine is able to search in any chm file no matter what language it is written.
Use browser extensions
What could be better than a web-browser to view web-pages?
CHMFox is an excellent CHM file reader. It is much better than all the third party programs that others are suggesting, which are mostly lacking many web-browser capabilities that Firefox and alike have.
I initially suggested the CHM reader extension for Firefox, but it isn't actively maintained anymore.
As an alternative, since the CHM format is not very popular you can convert it to PDF using
sudo apt-get install chm2pdf chm2pdf --webpage your.chm
This will produce a
your.pdf file. As an alternative you can use the
--continuous options instead of
--webpage; more info here http://www.ubuntugeek.com/how-to-convert-chm-files-into-pdf-files-in-ubuntu.html
Also a plugin called CHM Reader exists for Firefox.
In addition to the Firefox extension(s), there's a neat Chrome app called Chumium that does the job.
extract_chmLib does a very good job of converting chm (compiled html) files into htm format. It is in the Ubuntu repository in the package
extract_chmLib maintains the full functionality of the original.. However, I did need to rename files to lowercase, for one .chm (becaue
chm is a Windows format which is not case-sensitive like Linux), but the overall result is ideal for me...
Here are a couple of links...
Calibre is a library manager that can read all sorts of book formats, CHM included.
In Ubuntu Software Center you can do a search for "chm" (no quotes) and find some decent chm viewers.
However, while using them, I'm always missing the scaling features in firefox (to make everything bigger - not just fonts).
Therefore, my favorite CHM viewer is Firefox itself via the ChmFox extension.
