Command options

The Linux man pages provide an overview of the options and arguments for the nish command. The following table describes some of the options and flags that can be used when starting the NISH client.

Table 1. Options and flags for the nish command
Option or flag	Description	References
--credential-cache	Enables caching of SR OS node credentials in static or manager mode	See Authentication credentials
--ca-cert -t	Specifies TLS mode	See Configuring NISH security
--color NISH_COLORS	Specifies the color scheme for the NISH environment	See NISH rc files
--no-proxy	Disables system-defined proxy settings and ignores the http_proxy and https_proxy environment variables	—
--disable-auto-completion-authorization	Disables authorization checks for the auto-completion command ^¹	—

¹ Auto-completion ensures that only authorized commands are displayed in the auto-completion. The user's authorization to execute a command is checked against an authorization server or local profile. Disabling this option can improve performance but allows the auto-completion to display all commands, including the commands that cannot be executed because they fail authorization. Users are not able to execute commands for which they do not have authorization. See the 7450 ESS, 7750 SR, 7950 XRS, and VSR System Management Guide, section ‟Authorization” for more information.
