sh script combat

Do something or want to move as quickly as possible to the blog, or look back at your writing and have not read. . .

With memories + information search, when he started writing the script sh process of writing up.

First create a new .sh file, you can use vim

In the first line of sh, write

#!/bin/sh

This tells the system that this file is a script file. Must have

Then you can think of it as a console, you need to how to operate in the console, you can put the command as it posted here.

For example, create a file:

cd ~/Downloads
mkdir Geronimo

You can also run other scripts in sh sh in:

sh pcapname.sh ~/Downloads/Geronimo

This command is run pcapname script and pass in the path parameter ~ / Downloads / Geronimo

In pcapname.sh, the $ 1 is the passed parameters, i.e., ~ / Downloads / Geronimo, if additional parameters passed, that is, $ 2, $ 3 so

And to operate on all the files $ 1 folder:

for var in $1/*
do
    echo $var
done

But here is an integer of $ var path: ~ / Downloads / Geronimo / filename

So when you need to get the file name when the need to extract strings.

filepath=${var%.*}
filename=${filepath##*/}

filepath here is that in addition to the string name suffix, filename is removed / file name to the left of all strings.

String patch is required, as follows:

tcpfile=$filepath/${filename}_TCP.txt

$ Quoted string needs to be added, but in order not to be confused with the string behind the outer added {filename}.

sh interception string concatenation and may reference herein

Practical part:

I use tranalyzer extract features from traffic flow to generate _flows.txt files and _pl_iat.txt files, use a script to extract all the tawk tcp features from _flows.txt file in linux.

My traffic mei1 and mei2 folders, each folder under the 50 sub-folder, contains 50 kinds of traffic, there are 20 pcap files in each subfolder

For each flow, extract flows, pl_iat, tcp content, into the three folders, each folder 50 generated .txt files, wherein each file contains .txt 20 pcap files subfolders .

I used three layers .sh file called, respectively main.sh, pcapname.sh, extractor.sh

main.sh

#! / bin / incl
 mkdir / mnt / hgfs / mei / mei1 / mei1
 mkdir / mnt / hgfs / mei / mei1 / mei1 / flowsfiles
 mkdir / mnt / hgfs / mei / mei1 / mei1 / tcpfiles
 mkdir / mnt / hgfs / mei / mei1 / mei1 / pl_iatfiles 

mkdir / mnt / hgfs / mei / mei2 / mei2
 mkdir / mnt / hgfs / mei / mei2 / mei2 / flowsfiles
 mkdir / mnt / hgfs / mei / mei2 / mei2 / tcpfiles
 mkdir / mnt / hgfs / mei / mei2 / mei2 / pl_iatfiles 

including pcapname .sh / mnt / hgfs / mei / mei1 
including pcapname .sh / mnt / hgfs / mei / mei2

Here you can actually write cycle to achieve, but when the time of emergency, use the awkward, not much anyway

pcapname.sh

#!/bin/sh

#$1 is the directory of the upper level file of the .pcap file
#var is the name of the directory of the .pcap file 
# ${var#*ww_} remove the prefix, and input it to the extractor.sh
for var in $1/*
do
        sh extractor.sh $var ${var#*ww_} $1/${1##*/}
done

Here used to get the name of each sub-folders, each folder name form is WWW_52PK_com, I need to extract keywords 52PK

.extractor.sh

#!/bin/sh

#$1 is the directory of the .pcap file(don't including the ***.pcap file)
#$2 is the name of the directory of the .pcap file(remove the prefix name)
#var is the name of the .pcap file



for var in $1/*
do
        filepath=${var%.*}
        filename=${filepath##*/}

        #cd ~/Downloads/tranalyzer2-0.8.2lm2/tranalyzer2-0.8.2/trunk/tranalyzer2/src/
        #./tranalyzer -r $var -w $filepath/

        #cd ~/Downloads/tranalyzer2-0.8.2lm2/tranalyzer2-0.8.2/trunk/scripts/tawk/
        flowsfile=$filepath/${filename}_flows.txt
        tcpfile=$filepath/${filename}_TCP.txt
        pl_iatfile=$filepath/${filename}_pl_iat.txt
        #./tawk 'tcp()' $flowsfile > $tcpfile

        #./tawk -t -H '{
        #        n = split($L2L3L4Pl_Iat,A,";");
        #       for(i=1;i<=n;i++){
        #               split(A[i],B,"_");
        #               printf "%f\t%d\t",B[2],B[1];
        #       }

        cp $flowsfile $3/flowsfiles/$2_${flowsfile##*/}
        cp $tcpfile $3/tcpfiles/$2_${tcpfile##*/}
        cp $pl_iatfile $3/pl_iatfiles/$2_${pl_iatfile##*/}

done
