Right now, if I type
whereis on an executable that I'm interested in knowing the location, I get back several results where this software is located. What configuration can be done to get the last result at the front of the list?
If I'm running
whereis gcc, I may have 5 different versions of
gcc on the OS, but the highest/most-recent version displays last in the results of
whereis gcc, so it's not the preferred version of
gcc. So even though I have version 7.1 of GCC, running
gcc -v displays the lowest version that's installed on my box.
