I read here (second comment to the question)
When should I use \input vs. \include?
that \@input
"does not throw an error if the file does not exist".
If I try
\documentclass{article}
\begin{document}
\@input{toBeIncluded.tex}
\end{document}
I indeed get no fatal error, but still i get 3 compilation errors and, more importanly, my pdf contains the word "inputtoBeIncluded.tex".
Is there a simple way to completely ignore the input command if the input file does not exist?
Thanks a lot

You need to add
\makeatletter
to enable the use of the symbol@
in a macro.EDIT
As noted by @Emil Jeřábek, this has the side effect of changing the catcode of @ whilst
myfile.tex
is being read. This is unlikely to have any adverse effects, but it could be avoided as follows:That said, it's probably better to use
\InputIfFileExists{file}{}{}
, as suggested by @daleif.
