[Dev-luatex] Unknown command "mv -v" on Solaris

Hi, LuaTeX build fails on Solaris due to "mv -v" in build.sh: if [ "$BUILDLUA52" = "FALSE" ] && [ "$BUILDLUA53" = "TRUE" ] then mv -v "$B"/texk/web2c/$LUATEXEXE53 "$B"/texk/web2c/$LUATEXEXE ls -l "$B"/texk/web2c/$LUATEXEXE fi mv: illegal option -- v Usage: mv [-f] [-i] f1 f2 mv [-f] [-i] f1 ... fn d1 mv [-f] [-i] d1 d2 build/texk/web2c/luatex: No such file or directory Can you please perhaps store the command and echo it before executing it instead of calling "mv -v" which is apparently not portable enough? Thank you, Mojca
