EXOS 'cat' utility

Dave_Hammers — Tue, 10 Apr 2018 17:07:00 GMT

To create a linux like 'cat' utility in EXOS 22.4 and later:

in the exshrc.xsf file add the following line (or create the exshrc.xsf file)

alias cat "run script shell.py cd /usr/local/cfg;cat"Then the next time you login, the 'cat' alias will be available.

E.g.
# cat exshrc.xsf
alias cat "run script shell.py cd /usr/local/cfg;cat"E.g.
Suppose there is a file my.pol.
# cat my.pol
entry one {
if {
source-address 1.1.1.1/32;
} then {
meter joe1;
}}
entry two {
if {
source-address 1.1.1.2/32;
} then {
meter joe1;
}}

Nice!
Now we need an text edit (vi) command...
...and this seems to do it:
alias edit='run script shell.py cd /usr/local/cfg;vi'

Since

code:

vi

is already available, a simpler line is:

code:

alias edit "vi"

running vi in this mode restricts the filenames to specific suffix types
E.g.
vi abc.x
Error: Invalid XOS Cli file extension with vi.
Extension .pkt, .pol, .py, .xml, or .xsf is required.vs.
edit abc.xwith Ludovico's alias

Either of these aliases might cause some weirdness with the 'edit policy ' command. That said, you can just do 'vi ' or (with the alias) 'edit ' instead.

Did not realize that vi was already there...
But yes, my alias works:

EXOS-VM.37 #% cat test.cfgthis is my test
EXOS-VM.38 #% edit test.cfgthis is my test
~
...whereas vi directly does not:

EXOS-VM.38 #% vi test.cfgError: Invalid XOS Cli file extension with vi. Extension .pkt, .pol, .py, .xml, or .xsf is required.
