I want to exclude (-v) blank records from a file before analysing it.
I know I can use '^]$' for spaces and tabs but how do you look for lines that have nothing (/n or line feed) ? (2 Replies)
Wants to print line when there exist leading or trailing space or tab in fields 2,3 and 5
The below code prints all lines in file even if they dont have leading and trailing space or tab.

Hello,
Is there a direct command to check if the delimiter in your file is a tab or a space? And how can they be converted from one to another.
Thanks,

Hi, I want to read lines from a file, and I'm using two methods
1 use
while read line
do

2 use

however, in both of them, I notice that the tab between fields are automatically converted to space
because I want to use awk over the... (10 Replies)
Hi,
I have a space delimited text file but I only want to change the first space to a tab and keep the rest of the spaces intact. How do I go about doing that? Thanks! (3 Replies)
I have a variable sumOfJEOutputFile which is the output file of an SQL command which contains the output of that SQL. The output looks like below:

ssh-keychain
SSH-KEYCHAIN(8) BSD System Manager's Manual SSH-KEYCHAIN(8)NAME
ssh-keychain.dylib -- smartcard/keychain support library
DESCRIPTION
The ssh-keychain.dylib library is used as a PKCS11 module replacement for the family of ssh tools. It provides certificates on SmartCards
and/or in user keychains to the tools.
OVERVIEW
By default, all valid certificates from all SmartCards currently inserted into attached readers are provided. Manual configuration of
ssh-keychain.dylib is required if certificates in user keychains are desired, or if there is a need to limit which SmartCard certificates are
provided. The public key hash is used to select which certificates should be provided. This hash is usually in hexadecimal string form,
without the leading 0x. To determine the hash for certificate on a SmartCard, the sc_auth hash or sc_auth identities commands can be used.
For certificates in user keychains, it is the value of the hpky attribute from security find-certificate output.
ENVIRONMENT
Configuration passed through the environment always takes precedence over the configuration file. The variable KEYCHAIN_CERTIFICATES is used
to specify hashes. It should contain a semicolon-separated list of public key hashes of certificates which will be provided to the ssh tools.
CONFIG FILE
If no enviroment variable configuration is provided, ssh-keychain.dylib looks for a configuration file located at ~/.ssh/sshkeychain.plist.
This file is a standard property-list with a dictionary root object. It should contain the key KeychainCertificates with a value that is
either a string or an array of strings. If a string, then the expected value is semicolon-separated list of public key hashes like the envi-
ronment variable. If the value is an array, then each hash is an array entry.
EXAMPLES
Environment:
KEYCHAIN_CERTIFICATES="AE31125DA4AAA294A4FED97B815D7F8DD1A78FF3;168D2C4CDDFCDADD465BAF3E6BCFE8193D8D42D1"
ssh -o PKCS11Provider=/usr/lib/ssh-keychain.dylib machine
Configuration plist:
{
"KeychainCertificates" => [
0 => "AE31125DA4AAA294A4FED97B815D7F8DD1A78FF3"
1 => "168D2C4CDDFCDADD465BAF3E6BCFE8193D8D42D1"
]
