Hello onenessboy,

It is working fine for me as follows. I am attaching screen shot for same too.
Since NOT able to copy/paste screen shot here.

Thanks,
R. Singh

You could THANK people by hitting THANKS button on left corner of each post. Could you please try following.


tac Input_file | awk 'FNR!=2 && FNR!=3' | tac


Let me know if this helps you.

Hello onenessboy,

Could you please try following once.


tac Input_file | awk 'FNR==2{sub("static","dynamic")} FNR==3{sub("gnutls","ls")} 1' | tac


In case you want to save output into...

If the loop goes over the running processes, how are the not running processes detected then?
The following loops over the files to get the DB instances, then looks them up in the ps output:

You can also separate with a newline, and you can use two -e options for sed, and I think you want to insert \ characters
escapedText=$(
echo "$text
$text1" | sed -e 's/"/\\"/g' -e "s/'/\\\\'/g"...

Your code fragment: echo $text | $text1 is piping the output from echo $text into the command specified by $text1. From your description, that doesn't seem to be what you want to do. If you had...

Hi,

Instead of;

escapedText=$(echo $text | $text1 | sed 's/"/\"/g' | sed "s/'/\'/g" )


Try;

escapedText=$(echo "$text $text1" | sed 's/"/\"/g' | sed "s/'/\'/g" )

Just thinking about this in the wider question, you might (on you local machine) have to do this:-ssh bob@server "sudo -u oracle /path/to/your/script".... or perhaps:-ssh -t bob@server "sudo -u...

You don't add oracle to the wheel group. You need to allow your account to execute as oracle. Say your account is bob, then the entry in /etc/sudoers (or perhaps under /etc/sudoers.d/* could be...

Sorry to have been imprecise - you should have left KnownTime = T[1]

PCT=0.4 defines the necessary free space... this minus the actually available space yields the files' sizes to be deleted.

Assuming the stat command on your system allows for the -f (--file-system) option, and shamelessly stealing from Don Cragun's earlier post, and NOT being able to ultimately test this on my system,...

Hi onenessboy,
You can start by showing us the complete, exact output produced by the command:df -P /backup
If the output from the above command doesn't complain about an unknown -P option, the...

Talking about simplifying, why not


ls -r1 2[0-9][0-9][0-9][01][0-9][0-3][0-9]_[0-2][0-9][0-5][0-9].tar.gz | awk -F_ 'T[$1]++ {print "echo rm " $0}' | sh

I would be tempted to try a slightly simpler pipeline for what RudiC suggested:
ls -1 2[0-9][0-9][0-9][01][0-9][0-3][0-9]_[0-2][0-9][0-5][0-9].tar.gz |
awk -F_ '
$1 == last {
print "echo rm "...

How about


ls 2018* | sort -ur -k1,1 -t_ | cut -d_ -f1 | while read TS; do echo rm $(ls -r $TS* | tail -n +2); done
rm 20180721_0212.tar.gz 20180721_0112.tar.gz 20180721_0012.tar.gz

Generally the way you try it is the way it works.


What's the error message?

A bit overcomplicated, no? A for loop for a single file, two sed invocations in lieu of one. . . Why not (untested)

sh /home/centos/du.sh | sed '1,124d; s/.$//' > /home/centos/abc.csv

Please use code tags.

tail:
du.sh | tail -n +4
sed:
du.sh | sed '1,3d'
awk:
du.sh | awk 'NR>3'
There may be others.

Try awk '{for (i=1; i<=NF; i++) if ($i ~ /system/) print $i}'.

EDIT: The struck through if was because I misread your spec to only contain system related tables...

Try

df -h / | awk ' {printf "%s, %s\n" , $2+0, $3+0}' and also start to use printf's format string correctly.
The second question I do not understand - what else could it display?

A for loop cycles over the script arguments by default:
bkp_name="bkp-$$"
data_dir="/var/lib/data/"
for keyspace
do
echo do something with "$keyspace"
done
Replace the echo command with the...

Please use code tags.

You got one bit backwards, so your program ends up throwing away the first argument before you use it. Try reversing these two lines.

#!/bin/bash
echo "arg count = $#"
