I have a simple script:
#!/bin/bash
#
index=0
total=0
names=()
ip=()
while read -r LINE
do
NODENAME=` echo $LINE | cut -f 1 -d ','`
IP=` echo $LINE | cut -f 2 -d ','`
names[index]="$NODENAME"
ip[index]="$IP"
index=`expr index+1`
total=`expr total+1`
done <<< $(cat list.txt)
simple file:
more list.txt
name1,ip1
name2,ip2
name3,ip3
output when running:
sh -x ./test_bash.sh
+ index=0
+ total=0
+ names=()
+ ip=()
++ cat list.txt
+ read -r LINE
++ echo name1,ip1 name2,ip2 name3,ip3
++ cut -f 1 -d ,
+ NODENAME=name1
++ echo name1,ip1 name2,ip2 name3,ip3
++ cut -f 2 -d ,
+ IP='ip1 name2'
+ names[index]=name1
+ ip[index]='ip1 name2'
++ expr index+1
+ index=index+1
++ expr total+1
+ total=total+1
+ read -r LINE
+ echo name1
name1
Question is why is it not reading one line at a time ?
All I get is the first one.
I'm just trying to build the array of the items in the file and then list
them at this point.
Thanks
Jerry
