Checking for a null column in a csv file | awk -F '\\|' '$3==""' file.txt

By OK -
I have a delimited file with the following syntax:

A|B|C|D|E
How to find the count of records having null (empty) value in their third column in every ro

One way:
awk -F"|" '{if (length($3) == 0) ++count } END { print count }' yourfile
% cat file.txt
A|B|C|D|E
A|B|C|D|E
A|B||D|E

% awk -F '\\|' '$3==""' file.txt
A|B||D|E

Redhat recommends us to add  _netdev  option for NFS file system in /etc/fstab. So that they can be mounted after starting the networking service. Alternative ways to refer to partitions: Label : LABEL=label Network ID Samba : //server/share NFS : server:/share SSHFS : sshfs#user@server:/share Device : /dev/sdxy (not recommended) Example #1 //192.168.1.134/share_name /mnt/share_name cifs username=server_user,password=server_password,_netdev 0 0 ^ Path to your share ^ Mountpoint ^ Username ^ Password ^ See note A Note A: The  _netdev  options makes sure the mount is only attempted AFTER a network connection has been established. Example #2 10.10.10.1:/vol1/fs1 /data nfs defaults,_netdev 0 0 ============================ [root@localhost ~]# firewall-cmd --list-all public   target: default   icmp-block-inversion: no   interfaces:   sources:   services: dhcpv6-client high-availability ssh   ports:   protocols:   masquera
