i need to use above in a zgrep command

I'd like to determine in my bash script which NIC the default gateway is on in order to determine if i need to add static routes via the script or not. Since there are two instances of 0.0.0.0 in the routing table where the default gateway is I'n trying to determine the NIC mentioned in the routing table where there are two instances of 0.0.0.0. Then if it matches ${DftNic} below I no I won't have to add static routes on the server. Scratching my head on this so any help would terrific.

DftNic=$(ip route show | grep default  awk '{print $7}')

See: https://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewritecond

-h
Is symbolic link, bash convention.
See -l.

-l
Is symbolic link.
Treats the TestString as a pathname and tests whether or not it exists, and is a symbolic link. May also use the bash convention of -L or -h if there's a possibility of confusion such as when using the -lt or -le tests.

-L
Is symbolic link, bash convention.
See -l

What are the differences between these three?

"-h" has "bash concention" and "-l" not. But what is the difference in practise? Can someone give me an example of the difference?

And why it's "-L" and not "-H"? "-L" is about the bash convention, but "-l" not. However, "-h" is. So then I would expect "-H" instead of "-L".

I don't need it for something right now, but I'm trying to understand the Apache documentation.

I have multiple NICs on my Redhat 6 x86_64 server and as part of my script I have to determine which NIC is the default gateway on each server since there are lots of static routes over the other NICS. I always see the default gateway as the last line in the routing table but is that logic flawed and I just run net stat -rn | tail -1 | awk '{print $8}' but I'm not sure if that logic is up to par and I'm going to have to tally it up with what's in /etc/sysconfig/network as the gateway.

Hi,

I'm running CentOS Linux release 7.4.1708 (Core), issue is i'm able to login using local users but not using ldap users, please help me on this.

I've tried restarting services using authconfig-tui command, but still i'm getting authentication failure error for ldap user.

I have an RHEL5 VM that reboots on kernel panics. The VM hangs while rebooting at different stages of the bootup process.
I noticed the console shows the cursor blinking but stays stuck booting up and does not progress.

Any ideas on how to troubleshoot? The blinking cursor indicates the system is hung, correct?

1. Can someone explain me if there is any changes in .cloginrc file, I need to run the rancid-cvs and rancid-run,
2. When i am trying to login i can see that the username is not pulling from what is there in .cloginrc.

For Eg:
(Under my clogin file)
I have mentioned
add user 1x.x.x User1
add password 1x.x.x       {password}
add method 1x.x.x telnet ssh

But when i am trying to login, i can see that username is in rancid. I am not sure why its happening. And to make sure that if try firewall login or normal login, its going with actual username only
