I want to monitor the network interrupt(centos 6.5).
As mentioned above,we lost icmp_seq=2,How to locate the gap.
Search Stack again...
Say you have an input file named gaps
more gaps
icmp_seq=1
icmp_seq=2
icmp_seq=3
icmp_seq=5
icmp_seq=8
icmp_seq=10
You can make use of the below AWK
awk -F "=" '$2!=p+1{print p+1"-"$2-1}{p=$2}' gaps
4-4
6-7
9-9
explanations
-F "=" use = as the field separator
$2 is the second column from current input line
p is the previous value of the last line
so ($2!=p+1) is a condition : if $2 is different than previous value +1, then :
this part is executed : {print p+1 "-" $2-1} : print previous value +1, the - character and second columns + 1
{p=$2} is executed for each lines : p is assigned to the current 2nd column

The program that generated it, sorted alphanumerically based on the name in the first column, but I would like to sort it based on a list of names in another file, and keep all the other data. The other file has other information, like contig length in column 2 (this file was produced with samtools faidx).
OHJ07_1_contig_25270 888266 96530655 60 61

Since each name has a different number of entries in the first file, what's the easiest way to deal with this? Preferably using bash
I haven't tried anything because I have literally no way to tackle this.
I would prepend each line of file that determines the order (from now on named index) with its line number, there is a way using awk , I used the answer written here https://superuser.com/questions/10201/how-can-i-prepend-a-line-number-and-tab-to-each-line-of-a-text-file to do this (assuming your index file is named index and data file is named data.txt):
awk '{printf "%d,%s\n", NR, $0}' < index > index-numbered
in this way you will have in index-numbered a correspondence between the arbitrary words order you decided and numbers.
you can then use a while on file to sort that replaces each first word with index line number, a comma and the rest of line (keeping name) , for example :
57,OHJ07_1_contig_46339 411691 143341916 60 61
in this way you will be able to sort using the first field, the number, which translates your arbitrary order in a numeric order.
The while which create a new data file with same numbers as above:
while read line
do
key=$(echo $line | cut -f1)
n=$(grep $key index-numbered | cut -d, -f1)
echo $n","$line >> indexed-data.txt
done < data.txt
Then you can simply sort your modified data file (indexed-data.txt) using sort and using the inserted line number as sort key :
sort -k1 -n -t, indexed-data.txt >sorted-data.txt
If you want to hide line numbers on final output you can filter each one out modifying preceding instructions with these :
sort -k1 -n -t, indexed-data.txt | cut -d, -f2 > sorted-data.txt
Your final output will be in file sorted-data.txt .
I'm sure this is not the best solution, maybe others can answer better than me.
I'm trying to create script which will ping to remote server and displays only
1) % packet loss
2) average round trip latency in ms
for packet loss i created line
`ping -c 3 -s 14 x.x.x.x|grep packet|awk '{print $7}'|cut -d'%' -f1`
which only gives packet loss,
my problem starts when ip is not reachable output of line changes
and hence i'm not able to capture both
for reference i'm showing output of both scenarios
`/pefmephbir >ping -c 3 -s 14 10.9.50.225`
PING 10.9.50.225 (10.9.50.225): 14 data bytes
--- 10.9.50.225 ping statistics ---
**3 packets transmitted, 0 packets received, 100% packet loss**
`/pefmephbir >ping -c 3 -s 14 10.9.50.220`
PING 10.9.50.220 (10.9.50.220): 14 data bytes
22 bytes from 10.9.50.220: icmp_seq=0 ttl=63 time=0 ms
22 bytes from 10.9.50.220: icmp_seq=1 ttl=63 time=0 ms
22 bytes from 10.9.50.220: icmp_seq=2 ttl=63 time=0 ms
--- 10.9.50.220 ping statistics ---
**3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 0/0/0 ms**
hope someone with expertise in scripting can help me out
TIA
Try this:
ping ... | awk '/packet loss/{x="Loss:" $7} /round-trip/{x="Trip:" $4} END{print x}'
If it sees a line with "packet loss" in it, it creates a string x with the packet loss percentage. If it sees a line with "round-trip" it overwrites the string x with the round trip time. At the end, it prints whatever the string x is set to.
In the light of your comments...
awk '/packet loss/ && /100/{x="Loss: " $7} /round-trip/{split($4,a,/\//);x="Ave: " a[2]} END{print x}'
So, now the "packet loss" line must also contain "100" before we pick it up. And the 4th field of the "round-trip" line is split into an array a[] using / as separator, then we take the second element of a[] as the average and store that in our output string x.
Using sed:
ping ... | sed -n -e 's/.*\(100% packet loss\).*/\1/p' \
-e 's_.*min/avg/max = [0-9]*/\([0-9]*\)/[0-9]*.*_\1_p'

Thank you for your helps.
sort myFile.txt | uniq -c | awk '{ print $2 " " $1}' > myNewFile.txt
Edit: added sort and removed cat to take comments into account
And if you want only values which appear at least 4 times:
sort temp.txt | uniq -c | sort -n | egrep -v "^ *[0-3] " | awk '{ print $2 " " $1}'
Imagine your file is called t
You can do with:
cat t | sort -u | while read line #read each one element in sorted and uniqye
do
echo -n $line; # print element
cat t | grep ${line} | wc -l # read file, get only the specified and count
done

print only count >=4:
kent$ awk '{a[$0]++}END{for(x in a)if(a[x]>=4)print x, a[x]}' f

I was wondering how to extract only certain data from the output of a shell command in Applescript. I want to be able to only pass the IP address into the variable from a "ping -o" command like this:
do shell script "ping -o " & blockedURL
-- Set the IP to blockedIP --
set blockedIP to ..
but I receive this:
"PING example.com (192.0.43.10): 56 data bytes 64 bytes from
192.0.43.10: icmp_seq=0 ttl=239 time=101.587 ms
--- example.com ping statistics --- 1 packets transmitted, 1 packets received, 0.0% packet loss round-trip min/avg/max/stddev =
101.587/101.587/101.587/0.000 ms"
When I execute the ping command I receive a lot of data I dont need. Is there any way of being able to only recall the (192.0.43.10)?
set a to "PING example.com (192.0.43.10): 56 data bytes 64 bytes from 192.0.43.10: icmp_seq=0 ttl=239 time=101.587 ms
--- example.com ping statistics --- 1 packets transmitted, 1 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 101.587/101.587/101.587/0.000 ms"
set text item delimiters to "("
set temp to text item 2 of a
set text item delimiters to ")"
set temp to first text item of temp
return temp
The above is a full applescript solution. You can also use the following to get the IP just using the shell ping -o www.google.com | cut -d'(' -f2|cut -d')' -f1 | head -n1 so in applescript it would look like this :
do shell script "ping -o " & blockedURL & " | cut -d'(' -f2 | cut -d')' -f1 | head -n1"
