Full Discussion: Shell script to pass the config file lines as variable on the respective called function on a script
Top Forums Shell Programming and Scripting Shell script to pass the config file lines as variable on the respective called function on a script Post 303007126 by sadique.manzar on Sunday 12th of November 2017 06:44:59 AM
Old 11-12-2017
Code:
S1()
{
stream=S1
path=/sadique/S1
counter=0
while [ $counter -le 100 ]
do
	for  files in `printf "%s\n" $path/*.RTM | head -3`
	do

on above code i want to pass path from a config file where i have many values.
so i want that my script should read each line of config file and match the pattern with stream and pass the path variable in my code.



Config file :

Quote:

S1 /sadique/S1
IUPS /sadique/IUPS
IUCS /sadique/IUCS
---------- Post updated at 06:44 AM ---------- Previous update was at 12:39 AM ----------

Requirement:

Config file:

key1 path1
key2 path2

search the key while reading the config file.
take the 2nd column of the that line as path
and pass it value during run time.


Code:
##Read 1st column as key of all the lines match the key with key inside the function and pass the 2nd column as argument during run time
#!/bin/sh
DATE=`date +"%Y-%m-%d %H:%M:%S"`
S1()
{
key=S1
counter=0
while [ $counter -le 100 ]
do
	for  files in `printf "%s\n" $path/*.RTM | head -3`
	do
		if [[ -f $files ]];
		then
		TT_FIRST=`awk -F ',' 'NR==1{print $1}' $files`
		TT_LAST=`awk -F ',' 'END{print $1}' $files`
		FILENAME=`ls $files | cut -d '/' -f6`
		TIMESTAMP=$( date -r $files +'%s')
		FILE_CR_TIME=$( date +'%Y-%m-%d %H:%M:%S' -r $files)
        TRANS_TIME_FIRST=$(date -d @$(printf '%.0f\n' $TT_FIRST) +'%s')
		TRANS_TIME_LAST=$(date -d @$(printf '%.0f\n' $TT_LAST) +'%s')
		RECORD_TIME_FIRST=$(date -d @$(printf '%.0f\n' $TT_FIRST) +"%Y-%m-%d %H:%M:%S")
		RECORD_TIME_LAST=$(date -d @$(printf '%.0f\n' $TT_LAST) +"%Y-%m-%d %H:%M:%S")
		TIME_LAG_FIRST=$(expr $TIMESTAMP - $TRANS_TIME_FIRST)
		TIME_LAG_LAST=$(expr $TIMESTAMP - $TRANS_TIME_LAST)
		DELAY_PROCESS=$((`expr $(date -u +"%s") - $TIMESTAMP`))
		TRANS_DIFFTIME=$(expr $TRANS_TIME_LAST - $TRANS_TIME_FIRST)
		counter=100
		else
			echo "file doesn't exist" >/dev/null
		fi	
		if [ "${FILENAME}" != "" ]; 
		then
			echo "${DATE} ${stream} ${FILENAME} ${FILE_CR_TIME} ${RECORD_TIME_FIRST} ${TIME_LAG_FIRST} ${RECORD_TIME_LAST} ${TIME_LAG_LAST} ${DELAY_PROCESS} ${TRANS_DIFFTIME}" | hdfs dfs -appendToFile - /bigpfstest/DPI_INVESTIG/AUDIT/FINAL.csv
		else
			echo "Filename is empty" >/dev/null

nfanon

nfexpire(1)															       nfexpire(1)

NAME

       nfanon - netflow anonymisation

SYNOPSIS

       nfanon [options]

DESCRIPTION

       nfanon  is used to anonymise all IP addresses ( src, dst, next hop, router IP etc. ) in the netflow records using the CryptoPAn (Cryptogra-
       phy-based  Prefix-preserving Anonymization) module. The key -K is used to initialize the Rijndael cipher.  The key is either a 32 character
       string, or a 64 hex digit string starting with 0x.

	  See http://www.cc.gatech.edu/computing/Telecomm/cryptopan/ for more information about CryptoPAn.

       nfanon has several modes of operation.

       o  nfanon reads a sequence of input files, specified by -r, -R and -M and anonymises the flows in the given files. The input file arguments
       have the same syntax and meaning as nfdump(1).

       o nfanon reads a sequence of input files, specified by -r, -R and -M.  All anonymised flows are written to a single file specified by -w.

       o nfanon works as filter and reads flows from stding and writes the anonymised flows to stdout.

OPTIONS

       -r inputfile
	  Read input data from inputfile. Default is read from stdin.

       -R expr
	  Read input from a sequence of files in the same directory. expr may be one of:
	   /any/dir	     Read recursively all files in directory dir.
	   /dir/file	     Read all files beginning with file.
	   /dir/file1:file2  Read all files from file1 to file2.

	   Note: files are read in alphabetical sequence.

       -M expr
	  Read input from multiple directories. expr looks like: /any/path/to/dir1:dir2:dir3  etc.  and  will  be  expanded  to  the  directories:
	  /any/path/to/dir1, /any/path/to/dir2 and /any/path/to/dir3 Any number of colon separated directories may be given. The files to read are
	  specified by -r or -R and are expected to exist in all the given directories.  The options -r and -R must not contain any directory part
	  when used in conjunction with -M.

       -w outputfile
	  If specified writes anonymised netflow records to outputfile.

       -K key
	  The key is used to initialize the Rijndael cipher. key is either a 32 character string, or a 64 hex digit string starting with 0x.

RETURN VALUE

       Returns
	   0   No error.
	   255 Initialization failed.
	   250 Internal error.

NOTES

       None.
