I have this cronjob to run every minute
*/1 * * * * root sh /test.sh
My /test.sh logs the result of "top" and "free" command. It works fine when I run it manually on terminal with "sh /teste.sh" and saves the output to a nice file, however when the cron job runs it only saves the result of the command "free" below. Check this please:
printf "\n" >> "log_lojar_top_free.txt"
printf %s "$(date)" >> "log_lojar_top_free.txt"
printf '\t' >> "log_lojar_top_free.txt"
top -b -n 3 -d 1 | grep "Cpu" | tail -n 1 | awk '/^%Cpu\(s\)/ {printf $2}' >> "log_lojar_top_free.txt"
printf '\t' >> "log_lojar_top_free.txt"
free | awk '/^Mem:/ {printf $7}' >> "log_lojar_top_free.txt"
What is the error that is causing that only the last line (free) to have it's output loged?
/bin/bash
instead ofsh
, or by starting your script with a shebang line:#!/bin/bash
- see if it behaves better once you definitely have it running under bash and not some other shell. Another possibility is that you aren't looking in the right place for the output file. The cron job is running as root and since you didn't specify an output directory, only a file, it will probably save it at / - not a good place to use generally. Oh and BTW you don't need the /1.crond
writes to the user's home directory. In my case, for root that's/root
.
