Hi,

In general, if a command works at the shell prompt, it should work if that same command is put in a script that is run by that same shell. What might be happening here perhaps is that paths...

With any POSIX conforming shell, you could also do this entirely in the shell:
#!/bin/ksh
while IFS= read -r line
do printf 'Processing %s\n' "$line"
set -- $line
ip=$1
tm=$2
shift 2...

Hello Zooma,

Could you please try following too and let us know if this helps.
Let's say following is Input_file.

18:70:9f:e3:80:aa 10:11:15 My Wi-Fi Network 2437
18:70:9f:e3:80:aa 10:11:15...

If it's not comma-separated, it's not CSV. You've got a flatfile.

awk '{ S=""; for(N=3; N<NF; N++) S=S "_" $N ; print $1, $2, substr(S,2), $NF }' inputfile

I'm glad that you got it to work. With your updated scripts, what happens if you just use:
0-59/5 * * * * /usr/myFolder/start.sh
(leaving off the &)? If you're trying to avoid having cron send...

That's what cron is made for, given its "features" are dealt with, e.g. sourcing various .profile scripts in the beginning of your scripts, as proposed above.
How exact does the start of the various...

Just using /etc/profile to set the environment for a user's cron job probably isn't going to help much. There is a good chance you'll also need the user $HOME/.profile, $HOME/.bashrc, or some other...

cron uses a very minimal path. I suggest setting your own PATH, or sourcing /etc/profile, in your scripts or it may not find all the commands they need.

0-59/5 * * * * . /etc/profile ;...

Hello Zooma,

If you want your script to run each 5th minute then could you please try following into your crontab by doing crontab -eand let us know if this helps you.
...

Any error messages? I guess it starts but doesn't find the two scripts called. cron only provides a minimalistic environment, so you need to either define your own or use absolute pathnames for...

That's pretty much what cron already does for you -- sleeps an exact interval, corrects, and runs your program.

Can you insert a sleep command into the loop? If it kicked off a background job every five minutes, sleep 300 would do the job. If every five minutes was a definite goal, code to create a time five...

Use cron to run things you're scheduling regularly, put it in your crontab(crontab -e) like this:

0-59/5 * * * * /path/to/script.sh

Edit your cron table with cron -e. If you get errors, try...

Note that your script:
#!/bin/bash
awk '
{
if(!($1 in c))
{
colors[$1] = $1
}
TotalValue[$1] += $2
occurrences[$1]++
}

END { ...

Hello Zooma,

You could try following too and let us know how it goes for you.

awk 'BEGIN{print "Color Occurrence Mean Value" ORS "===== ============ =========="}...

- the array c is not populated; I guess you want to use colors
- occurrences is misspelled/inconsistently spelled in different places
- the %12d format can't print decimals for mean values

Try...

Actually one: put "\n" at the end of your printf()s, because linefeeds do not come automatically. ;-))

I hope this helps.

Yes. Use something like the curl(1) (https://www.unix.com/man-page/all/1/curl) command.

Dynamic case:awk '
FNR==NR {a[$1]=$2
d="-"
for (i=3; i<=NF; i++) {a[$1]=a[$1] FS $i; d=d FS "-"}
next
}
...

If you sort your files you can then use join:

$ join -j 1 -e "-" -a 1 -a 2 -o 0,1.2,1.3,2.2,2.3,2.4 file1.sor file2.sor
Blackberry dark 4 sour 4 3
Blueberry blue 14 tasty 12 78
Raspberry red 12...

You're not too far off:awk 'FNR==NR{a[$1]=$2 FS $3 FS $4;next}{ print $0, a[$1]?a[$1]:"- -"; delete a[$1]} END {for (i in a) print i, "- -", a[i]}' file2 file1
Blueberry blue 14 tasty 12 78...

Hopefully, you'll see how easy all of these pieces fit together soon...
awk -v A="$(date "+%y%m%d %T")" '{print A,$0}' file.txt

And, if someone is using a shell that doesn't accept $(<file), and file1.txt just contains one line, you could use:
IFS= read -r A < file1.txt; awk -v A="$A" '{print A,$0}' file.txtor, entirely in...

If you get an error message, prevent word splitting with quotes: ... A="$(<file1.txt)" ...

If post #3 did not produce an error then this should work, too.
awk -v A=$(<file1.txt) '{print A,$0}' file.txt
