Delete first column in tab-delimited text-file
I have a large text-file with tab-delimited genetic data that looks like:
KSC112 KSC234 0 0 1 1 A G C T
I simply wan to delete the first column, but since the file has 600 000 columns, it is not possible with awk (seems to be limited at 32k columns).
Does anyone have an idea how to do this?
