Shell script to pass the config file lines as variable on the respective called function on a script

I want to make a config file which contain all the paths.
i want to read the config file line by line and pass as an argument on my below function.
Replace all the path with reading config path line by line and pass in respective functions.
how can i achieve that?

Kindly guide.


Code:

#!/bin/sh
DATE=`date +"%Y-%m-%d %H:%M:%S"`   
S1()

stream=S1

counter=0
while [ $counter -le 100 ]

Can you condense this to a suitable working example to simply illustrate your question? There is too much to consider here in one go.



Thanks,

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)

as "config" files are named after the functions (or vice versa), you could use $FUNCNAME.
# 5  
Old 11-12-2017
Why can't you simply grep the config file.
Code:
grep IUPS configfile |read key newpath
PATH=$newpath; export PATH

did you try using a variable assigned from a pipe in /bin/sh ?
This User Gave Thanks to daPeach For This Post:

Old 11-16-2017
My requirement is

--Read the config file line by line
--lines contains 8 columns
--validate from 8th column saying status if 1 active else inactive.
--1st column should pass as stream
--2nd column as path
--3rd column as counter
--4th column as counterlimit
--5th column from the files inside the path 1st column of the file and 4th column condition wise.


Quote:
Firstly it will read each line and check the 8th column as status.
if status vale is 1
go to my function
pass each line in for loop.
1st column as argument saying stream
2nd column for path
3rd column counts.
4th column in if condition saying 3rd column less than equal to it.
5th column help to read each file of the path and from file read 1st column.
and further implement the logic.

Code:
latency()
{
stream=$1
path=$2
counter=$3
counterlimit=$4
while [ $counter -le $counterlimit ]
do
	for  files in `printf "%s\n" $path/*bna_1* | 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 
		fi 
	done

sleep 10s
done
}


ignore echo part fro  or a while now.
