Juniper CLI - make your work faster

In this next lines you are going to read about some commands that can make your work with Junos easier
(Simple RegExp and Junos examples) 
This list is mainly for thought memorizing.

1. show interfaces in two lines list with MTU

show interfaces | match "mtu|interface:" |trim 19

 2. show interfaces without second line with logical interface with family
before:
[edit]
user@switch# run show interfaces terse                 
Interface               Admin Link Proto    Local                 Remote
ge-0/0/0                up    up  
ge-0/0/0.0              up    up   eth-switch
ge-0/0/1                up    up  
ge-0/0/1.0              up    up   eth-switch
ge-0/0/2                up    down
ge-0/0/2.0              up    down eth-switch
... output truncated

after:
[edit]
user@switch# run show interfaces terse |except "\."   
Interface               Admin Link Proto    Local                 Remote
ge-0/0/0                up    up 
ge-0/0/1                up    up 
ge-0/0/2                up    down
... output truncated


3. show ipv4 address on your switch or router, show only interfaces:
{master:2}
user@switch> show interfaces terse |match "inet "
ge-0/0/12.3212          up    up   inet     10.32.1.41/30  
ge-0/0/13.3200          up    up   inet     10.32.1.245/30 
ge-0/0/13.3202          up    up   inet     10.32.1.1/30   
ge-1/0/1.107            up    up   inet     xx.yyy.zz.1/30 
ge-1/0/13.3201          up    up   inet     10.32.1.249/30 
ge-1/0/13.3203          up    up   inet     10.32.1.5/30   
...

{master:2}
user@switch> show interfaces terse |match "inet " |trim 44
10.32.1.41/30  
10.32.1.245/30 
10.32.1.1/30   
xx.yyy.zz.1/30 
10.32.1.249/30 
10.32.1.5/30   
...

You could then save it to text file (add | save filename ad the end of command
show interfaces terse |match "inet " |trim 44 | save ipv4.txt

) and transfer your linux.Then do some things with it. For example calculate subnet address from ip address with ipcalc i.e.

ipcalc 10.32.1.41/30 | grep Network

...

So. I did a batch file
from file like this:
10.32.1.41/30  
10.32.1.245/30 


to file like this:

ipcalc 10.32.1.41/30 | grep Network >> networks.out
ipcalc 10.32.1.245/30 | grep Network >> networks.out

with this two commands:
sed -e 's/^/ipcalc /' ipv4.txt > networks.sed1
sed -e 's/$/| grep Network >> networks.out/' networks.sed1 > networks.sed2

chmod a+x networks.sed1
bash networks.sed1
hopefuly gives you

10.32.1.40/30

10.32.1.244/30


4. just another tidily  output for sflow interfaces (EX4200 Junos 10.0S10)
show interfaces terse |match "eth-switch|aenet" | match "ge|xe" | no-more
ge-0/0/0.0              up    up   eth-switch
ge-0/0/1.0              up    up   eth-switch
ge-0/0/2.0              up    up   eth-switch
ge-0/0/3.0              up    up   eth-switch
ge-0/0/4.0              up    up   eth-switch
ge-0/0/5.0              up    up   eth-switch
ge-0/0/6.0              up    up   eth-switch
ge-0/0/8.0              up    up   aenet    --> ae6.0
ge-0/0/10.0             up    up   eth-switch
... And you need to throw it edit it with spreadsheet or via bash or something else.
Remove text after space, then add string to beginning of line.
sed 's/ .*//;s/, .*//' sflow01.txt | sed s/^/"set protocols sflow interfaces "/
