How can I retrieve numeric value from text file in shell script? - bash

Question

below content has been written in a text file called test.txt. How can I retrieve pending & completed count value in shell script?
<p class="pending">Count: 0</p>
<p class="completed">Count: 0</p>
Here's what I tried:
#!/bin/bash
echo
echo 'Fetching job page and write to Jobs.txt file...'
curl -o Jobs.txt https://cms.test.com
completestatus=`grep "completed" /home/Jobs.txt | awk -F "<p|< p="">" '{print $2 }' | awk '{print $4 }'`
echo $completestatus
if [ "$completestatus" == 0 ]; then

grep and awk commands can almost always be combined into 1 awk command. And 2 awk commands can almost always be combined to 1 awk command also.
This solves your immediate problem (using a little awk type casting trickery).
completedStatus=$(echo "<p class="pending">Count: 0</p>^J
<p class="completed">Count: 0</p>" \
| awk -F : '/completed/{var=$2+0.0;print var}' )
echo completedStatus=$completedStatus
The output is
completedStatus=0
Note that you can combine grep and awk with
awk -F : '/completed/' test.txt
filters to just the completed line , output
<p class=completed>Count: 0</p>
When I added your -F argument, the output didn't change, i.e.
awk -F'<p|< p="">' '/completed/' test.txt
output
<p class=completed>Count: 0</p>
So I relied on using : as the -F (field separator). Now the output is
awk -F : '/completed/{print $2}'
output
0</p>
When performing a calculation, awk will read a value "looking" for a number at the front, if it finds a number, it will read the data until it finds a non-numeric (or if there is nothing left). So ...
awk -F : '/completed/{var=$2+0.0;print var}' test.txt
output
0
Finally we arrive at the solution above, wrap the code in a modern command-substitution, i.e. $( ... cmds ....) and send the output to the completedStatus= assignment.
In case you're thinking that the +0.0 addition is what is being output, you can change your file to show completed count = 10, and the output will be 10.

Answer 2

another awk
completedStatus=$(awk -F'[ :<]' '/completed/{print $(NF-1)}' file)

If I got you right, you just want to extract pending or completed and the value. If that is the case,
Then Using SED,
please check out below script.Output shared via picture, please click to see
#!/bin/bash
file="$1"
echo "Simple"
cat $1 |sed 's/^.*=\"\([a-z]*\)\">Count: \([0-9]\)<.*$/\1=\2/g'
echo "Pipe Separated"
cat $1 |sed 's/^.*=\"\([a-z]*\)\">Count: \([0-9]\)<.*$/\1|\2/g'
echo "CSV Style or comma separeted"
cat $1 |sed 's/^.*=\"\([a-z]*\)\">Count: \([0-9]\)<.*$/\1,\2/g'
