Question about: WARNING: file viewed via LESSOPEN

From looking through the source code, it appears the warning is issued if VISUAL is also defined. If you wish to, you can revise /usr/src/usr.bin/less/command.c to remove it.

[J65nko]

Instead of jggimi hint to patch less(1), you could try to use env(1) to empty the VISUAL environment variable. Something like:

$ env VISUAL=''" less

The problem with this workaround is that the VISUAL variable although set to nothing, it still exists. Don't know whether /usr/src/usr.bin/less/command.c can differentiate between VISUAL being set or being empty ;-)

[jggimi]

Perhaps $ unset VISUAL might work.
