I have script that is doing an iperf3 test against a server and is piping it into a file. Then I have this command, that takes makes a line for a logfile.
It works when executing on the command line, but not when it's running from crontab.
#!/bin/bash
printf "%s%sn"
"$(TZ=CEST date -d "$(head -1 some.log)" "+%y-%m-%d %H:%M:%S")"
"$(grep sender iperftmp.log | awk -F"] " 'print $2')" >>
/data/div/sh/somenew.log
In crontab it looks like this:
46,36,21,06 * * * * /bin/bash /path/to/print.sh >/dev/null 2>&1
I have tried many ideas in crontab -e, but it gives me the same error:
18-09-13 00:00:00
It should be:
18-09-13 15:20:11 0.00-10.00 sec 5.15 GBytes 4.42 Gbits/sec 1570 sender
Would you please advice?

I would start by directing stdout and stderr to a file, and maybe see actual error.

What implementation and version of cron are you using?

check paths to some.log and iperftmp.log, and make them full, not just filenames, as in cron you have different workdir, then normally
