It's the same as $NF - the last field in the input line regardless of its actual field number.
awk splits the line into n fields and then assigns n to NF (number of fields?) If you have three...

Hopefully it's correct :)

# On lines that meet condition -> if 'last' has a value and second field value of input is not equal to 'last'

This is the main loop that is run for each input record.
The variable "last" is tested for a value that was assigned in a previous loop cycle.
What happens in the first loop cycle? "last" is...

The file is /home/LOGS_2018-08-20.tar.gz and you are looking for /home/LOGS_18-08-20.tar.gz. Change the %y in your script to %Y and try again.

Does it work without echoing the $DATE variable?

Does it work when echoing the $DATE variable before the sftp command?

println() means "print line", it prints lines.

You could assemble the entire line you wanted to print before printing it.

A \n an embedded newline character (not two consecutive characters \ and n).
sed loops over the lines in the input file, so the sed code only has one line in its "pattern space".
The \n character...

what does 1h - as said before, you have addresses and commands; here: on first line, copy pattern space to hold space. Multiple addresses possible. and 1! - ! means negation; some...

The bit in red. Rudi said the space was in d.
Try this instead:
d=`date "+%Y%m%d %H:%M"`

In sed, and other tools such as grep and awk, [] is a character class - a character that can match anything inside the brackets. This can be a list, a range, or a combination of the two. If the first...

Hello scriptor,

Could you please go through the following explanation and let me know if this helps you.

Hello scriptor,

Could you please try following and let me know if this helps you.

You need to implement another authentication method, e.g. "public key authentication". Check man ssh, chapter "AUTHENTICATION".

man awk:gsub (/\|/, "\n" $1 ":")
r: /\|/, a regex constant, value: | (needs to be escaped with \ as | has a special meeting in extended regex)
s: string consisting of three substrings:
"\n":...

man awk: so, -vDT defines the variable DT to be used inside the awk script.

And, ~ DT is not an option, but the matching operator; $0 ~ DT checks for a match.

The assignment is for awk - not a shell assignment. Therefore needs quotes to prevent word splitting.
ls -l | awk -vDT="$(date +"%b %d")" '$0 ~ DT {print $9}'
Or use this precise one
ls -l | awk...

The same way the OS figures to which the OS figures out which file the link points to: it is stated in the command you use when creating the link. Suppose you create the link:

ln -s ./a ../b

1. $pwd/linkk
2. ln -s /home/guest/khare/AWK/linkk /home/guest/khare/AWK/done

On RAID3 the parity drive is fixed. So, for example, given the minimum of 3 drives, you get the usable capacity of 2 drives, and lose the capacity of 1 drive for parity. Similarly, if you had 50...

From man errpt

well, e.g. lets take your last line:
you cp what?

cp -p $( ls -lrt | grep 'Mar 26' | awk '{print $9}') /home/guest/khare/debug

OK?

@Scriptor: May be the script that you use could tell you what it is...

search for the "not a regular file".. there could be a check like below

[0-9]* zero or more...

What did you expect after reading Don's and my explanations (or - maybe - not?)? You have a space separated input and try to separate it by colons. The shell will of course use $x as one single lump...

There's no confusion, the two variables hold different values that represent different things, however if you need a trick to tell them apart, PATH is the path to be searched for executables when you...
