i would like to extract the pspictures from a tex file and put the in another file so they can processed into ps or pdf files really easily

Question

I have a list of files .tex file that contain fragments in the tex that build ps pictures which can be slow to process.

There are multiple fragments across multiple files and the end delimiter is \end{pspicture}

% this is the beginning of the fragment
\begin{pspicture}(0,0)(23,5)
\rput{0}(0,3){\crdKs}
\rput(1,3){\crdtres}
\rput(5,3){\crdAh}
\rput(6,3){\crdKh}
\rput(7,3){\crdsixh}
\rput(8,3){\crdtreh}
\rput(12,3){\crdQd}
\rput(13,3){\crdeigd}
\rput(14,3){\crdsixd}
\rput(15,3){\crdfived}
\rput(16,3){\crdtwod}
\rput(20,3){\crdKc}
\rput(21,3){\crdfourc}
\end{pspicture}

I would like to extract the fragments.

I am not sure how to go about this? can awk do this or sed?

They seem to work line by line, rather than work on the whole fragment.

I am not really looking for a solution just a good candidate tool.

Answer 1

sed -En '/^\\begin\{pspicture\}.*$/,/^\\end\{pspicture\}.*$/p' file

Utilising sed with -E for regular expressions.

Use //,// to determine start and ending regular expressions and print all lines from the start to the end.
