[LINUX] not injecting

[totkyle]

i tried the injection method for linux on the readme sudo gdb -batch-silent -p $(pidof cs2) -ex "call (void*)dlopen("$PWD/libOsiris.so", 2)"
it gave me the error: call (void*)dlopen("/home/arhan/Desktop/libOsiris.so", 2): No such file or directory.
Illegal process-id: -ex.
the file clearly exists, i am running cs2, after using this command in the task viewer cs2.exes name changes to MainThrd,
but there is no cheat loading at all, i used the shell script to inject for csgo osiris linux i edited it for cs2 but that didnt work either, please help.
