Following the instructions in this page https://help.ubuntu.com/community/LaTeX , I installed TexLive, which needs some 1GB of space (I installed the texlive-full package). Yet, after installation, I don't seem to find any command that seems to represent the TexLive!! Is it the normal tex, latex, pdflatex, etc.? Well, I already had those before installing TexLive? So where was the 1GB installed? What about the packages? Where were they installed?
You could use
kpathsea to check the locations.
Type this at the command prompt to get the main path of your TeX installation:
kpsewhich can provide more information, just type
kpsewhich --help to learn more about it.
Further you could use the
which tool to locate executables:
You may also check the versions of TeX, pdfTeX, LaTeX etc.:
tex -version latex -version
All can be done at the command prompt, i.e. within a terminal window.
Further there are of course package managing tools of your distribution for look-up which packages are installed - Synaptic,
dpkg-query -l etc.
If you're still not sure: just go ahead, compile a LaTeX file. Afterwards read the first line of the
.log file produced by LaTeX, within the same directory. The first line may look like:
This is pdfTeX, Version 3.1415926-1.40.10 (Web2C 2009) (format=pdflatex 2010.6.25) 12 DEC 2010 16:47
So you know if you're using a current version. The package manager which you used for installation should have taken care of all, so texlive would be used. The questions 'What' and 'Where' can be answered by the mentioned
kpsewhich, using various parameters, which does path look-up and file-look-up and presents the actually 'active' file.
If you installed
texlive from the Ubuntu repositories, the executables are in
/usr/bin while the documentation for the various packages are in
You may want to install the more updated version from the TeX Users Group, but then you must remember to add the path of the executables to your system then. Read the installation documentation for more information.
