IRIX Tips: 1/2020 - Raion - 01-26-2020

I'm gonna try and do some monthly tips threads on this. If they become popular enough, then I'll start a subforum for 'em.

• IRIX does have skeleton files that it uses to create a user account. These are located in /var/sysadm/config and can be used to add anything from a custom shellrc to populate in default files for programs like vim. 
  
• /usr/sysadm/privbin/ is a privileged user directory full of useful scripts to automate tasks. 
  
• MIPSPro is quite pedantic, so you can use -woff to turn off some of the warnings. That being said, it catches a lot of things GCC will let slide that could be serious issues down the like. Use the following at your own risk in a makefile
         NOWARN = -woff 1009,1014,1110,1116,1185,1188,1204,1230,1233 \                -Wl,-woff,85,-woff,84       $(CC) $(NOWARN) ...
  
• IRIX's main libc is only available as a shared object, so for a lot of programs calling from IRIX libc, full static linking isn't possible. 
  
• tcsh on IRIX is actually quite usable, and far faster than bash. Here's my .cshrc I use for root:
  
  Code:

  # User TCSH for IRIX

# ENV
setenv PATH '/usr/sbin:/usr/bsd:/sbin:/usr/bin:/etc:/usr/etc'

# Prompt
set     red="%{\033[1;31m%}"
set   green="%{\033[0;32m%}"
set  yellow="%{\033[1;33m%}"
set    blue="%{\033[1;34m%}"
set magenta="%{\033[1;35m%}"
set    cyan="%{\033[1;36m%}"
set   white="%{\033[0;37m%}"
set     end="%{\033[0m%}" # This is needed at the end... :(
set prompt="${yellow}%n${green}@%m ${yellow}%~ ${blue}%%${end} "

# Development
setenv CC c99
setenv CXX $CC
if ($?prompt) then
        # An interactive shell -- set some stuff up
        set filec
        set history = 1000
        set savehist = (1000 merge)
        set autolist = ambiguous
        # Use history to aid expansion
        set autoexpand
        set autorehash
        if ( $?tcsh ) then
                bindkey "^W" backward-delete-word
                bindkey -k up history-search-backward
                bindkey -k down history-search-forward
        endif

endif
• and .login:
  
  Code:

  # User .login for IRIX

# ENV
setenv TERM xterm
stty intr '^C'
stty erase '^?'
  
  
• You can change the prompt colors; I use the red to remind myself I'm root. 
  

Useful or not?
