login shell binary outside of /bin

2021-07-01 Thread Basin Ilya via Cygwin 
Hi
I compiled bash 5.1 and installed it to /usr/local

If I try to use it as a login shell it fails to launch programs while sourcing 
/etc/profile. If I copy the binary to /bin it works. If after successful login 
I launch `/usr/local/bin/bash5 -login` again it works. If I copy the official 
bash4 to /usr/local/bin and try to do the initial login it fails just like 
bash5.

Bad:

no regular expressions in less

2021-07-21 Thread Basin Ilya via Cygwin 
Hi list.
I've just noticed that regexp search works identically to exact match search in 
less and it prints this:

$ /usr/bin/less --version
less 581.2 (no regular expressions)
