如何通过genmon正确格式化df管道？

Question

I am having trouble with command output formatting.

In terminal this works nicely:

df | grep sda1 | head -c33 | tail -c7 | tr -d " "

In genmon, I get only numbers such as "1145944":

SDAFREE=$(df | grep sda1 | head -c33 | tail -c7 | tr -d " ")
echo="$SDAFREE"

How do I print that command's output through genmon to xfce panel correctly (same as in terminal)?

Thank you.

I have the same issue with every command with a pipe. As a workaround I put the command in a executable script and run the script in genmon.

BTW: if you want just one value of a table, you can use awk instead of head, tail and tr:

df | awk '/sda1/ {print $4}'
