Limits of length for the expansion of * in Bash? [duplicate]

Answer 1

The shell does not limit this

You can see the limit for your system with (run on my 64bit linux:)

$ getconf ARG_MAX
2097152

See this very informational page http://www.in-ulm.de/~mascheck/various/argmax/

Answer 2

I believe the command line limit is the value of ARG_MAX which you can see with

getconf ARG_MAX

This is not a bash variable, which would suggest that the limit is the same for echo in bash and /bin/echo.
