READ line by line a file 1

aoroca · Nov 20, 2003

How I can create a function that read line by line a file, and this data can be included in other script and performed activity, then continue with 2nd line.

FILE 1
192.168.23.4 Hola
198.65.45.6 Mundo

FILE 2 Script

get file 1 column 1 = 192.168.23.4
execute something with 192.168.23.4 and execute
echo " ALL file 1"

then ....

get file 2 column 1 = 192.168.23.4
execute something with 192.168.23.4 and execute
echo " ALL file 2"

This might give you a start

for the info in file f1
--------------
192.168.23.4 Hola
198.65.45.6 Mundo
--------------

This script
--------------------------------------------
typeset -i cnt=0

while read LINE
do
(( cnt = 1 ))
for FIELD in ${LINE}
do
echo "VALUE in field #${cnt} is -- ${FIELD}"
(( cnt = cnt + 1 ))
done
done <f1
--------------------------------------------
Should produce the following results
--------------------------------------------
VALUE in field #1 is -- 192.168.23.4
VALUE in field #2 is -- Hola
VALUE in field #1 is -- 198.65.45.6
VALUE in field #2 is -- Mundo

Try something like this in sh or ksh:

Code:

i=0 export i
while read ip buf
do
  i=`expr $i + 1`
  yourCommand $ip
  echo &quot; ALL file $i ($ip)&quot;
done<&quot;/path/to/FILE 1&quot;

How I can integrate your script with PHV script in order to read line by line and get a loop

PHV · Nov 21, 2003

Try something like this in sh or ksh:

Code:

i=0 export i
while IFS=',' read ip buf
do
  i=`expr $i + 1`
  yourCommand $ip
  echo &quot; ALL file $i ($ip , $buf)&quot;
  v1=$ip; v2=&quot;$ip , $buf&quot;
  doWhatYouWant $v1 &quot;$v2&quot;
done<&quot;/path/to/FILE 1&quot;

PHV Ok It looks good, thanks a lot, but i have one problem in myscript with some variable (ARRIBA=1), is it possible you can check and tellme why dont works 2nd part of my script when IP add is down and get UP.

Thank you

while [ $arriba ]
do

i=0 export i
while IFS=',' read ip buf

i=`expr $i + 1`
echo " ALL file $i ($ip , $buf)"

1st remark (without any understanding of what this script is supposed to do), they are 2 missing

Code:

fi

.
I guess they should be inserted here:

Code:

        echo &quot;`date` $MSG&quot; >> $path/NetLogChk
        arriba=0

fi

Code:

fi

Code:

    if [ $arriba -eq 0 ]

I have some problems. I use KSH and have problems with 2 variable, why:

if [ -z $a ]

if [ -n $a ]

How I can configure these 2 lines:

May be $a must be "$a",

a => some characteres

and I need know when $a is different to 0 and equal to 0 in long of chars, in order to check and perform the activities

PHV · Nov 24, 2003

As the variable a may be empty or have some embedded space, I agree the correct coding should be:

Code:

[ -z &quot;$a&quot; ] && echo empty
[ -n &quot;$a&quot; ] && echo non empty

to avoid side effect or even syntax error for the test builtin function.
Another syntax problem I can see is the escaped quote at the end of the 2 strings you print to sms_operator.
Finally, I think that the logic flow of the arriba is broken as is it the same variable for all your ip add.
IMHO you should use arrays, something like this:

Code:

#!/bin/ksh
path=$HOME/Alex
# Load the ip and inf arrays by reading ip_add.txt
eval $(awk -F',' '{
printf &quot;ip[%d]=\&quot;%s\&quot;;inf[%d]=\&quot;%s\&quot;\n&quot;,NR,$1,NR,$0
}' $path/ip_add.txt
# Preload arriba array with value 2 (unseen)
type -i nb=${#ip[*]} i=0
while [ $i -lt $nb ]; do
 i=$((1+i)); arriba[$i]=2
done
# Forever loop
while :; do
 # For each ip add loop
 i=0; while [ $i -lt $nb ]; do
  i=$((1+i)); SERVER=&quot;${ip[$i]}&quot;; SERVINF=&quot;${inf[$i]}&quot;
  echo &quot;ALL file $i ($SERVER,$SERVINF)&quot;
  a=`netstat | grep smpp | grep $SERVER | grep ESTABLISHED`
  t=${arriba[$i]}; MSG=&quot;&quot;
  if [ -z &quot;$a&quot; ]; then
   if [ $t -eq 1 -o $t -eq 2 ]; then
    t=0; MSG=&quot;SMSC::SMPP '($SERVINF)' is DOWN&quot;
   fi
  else
   if [ $t -eq 0 -o $t -eq 2 ]; then
    t=1; MSG=&quot;SMSC::SMPP '($SERVINF)' is UP&quot;
   fi
  fi
  if [ -n &quot;$MSG&quot; ]; then # State change
   for MOBILE in $(<$path/mobiles.txt); do
    print

YourSubmitStringHere

Code:

 |
     sms_operator >/dev/null 2>&1
    sleep 1
   done
   echo &quot;`date` $MSG&quot; >>$path/NetLogChk
   arriba[$i]=$t
  fi
  sleep 1
  done
done

With this draft you have to kill and restart the script if the ip_add.txt file changes.

Are you sure you use ksh as I suggested in previous post?

aoroca · Nov 27, 2003

Yes, I am working with KSH over AIX.
#!/bin/ksh

PHV · Nov 28, 2003

Soorry for the typo.
Replace the following line:

Code:

type -i nb=${#ip[*]} i=0

by this:

Code:

typeset -i nb=${#ip[*]} i=0

I change the script in typo's and add new info

print "submit\n$MOBILE\n\n5710000001\n\n\n\n\n\n\n\n\n\n\n\n$MSG\ny\nexit\n\"|
sms_operator >/dev/null 2>&1

but have problems with 35 line. why?
