How to format The mail Output of Bash Shell Script

Question

I have a Bash shell script which send an email in every day at certain time. the code is as follows:

first_dir=/test1 second_dir=/test2

[email protected]

allfiles=$(find /test1 /test2 -maxdepth 1 | sort) IFS=$'\n'

while true do sleep 24h

[ "$allfiles" != "" ] &&
    find $allfiles -maxdepth 1 -printf '%Tc\t%s\t%p\n' |
    mail -s "List Of All Files" "$email"

files="$allfiles"  

done

This script is giving output in Single column. but I want the Output in two columns.

1st column with files of first_dir=/test1
2nd column with files of second_dir=/test2

First: you should use crontab for scheduling for a certain time. This will execute every 24h at the time the script is started. — PeterMmm

@PeterMmm scheduling and running is not the issue. What i want is a clear list of files in the mail in two separate columns so that i can perform analysis easily — Readerlook

If you want them separated like that, don't join them together in the first place

first_dir=/test1
second_dir=/test2
while sleep 24h; do
    first_files=$(find $first_dir -maxdepth 1 -printf '%Tc\t%s\t%p\n')
    second_files=$(find $second_dir -maxdepth 1 -printf '%Tc\t%s\t%p\n')
    paste <(sort -t $'\t' -k 3,3 <<< "$first_files") \
          <(sort -t $'\t' -k 3,3 <<< "$second_files") |
    mail -s "List Of All Files" "$email"
done

👍 This would be even better without the sleep and in a cron job.

YES I will use cron in that.

As mentioned earlier... the basic need/requirement is a clear list of files in two directories in one email.

You want to use | instead of \t? OK, then do it. It's that simple.
