Hi guys,
I'm stil not sure if this is a terminal issue or something wrong with
progress-bar.sh (not an issue with PIDs, thankfully :). Sometimes I'll
come back and the bar is progressing across AND down the screen. Seems
to only happen for really long running targets. Potentially, the 100
min mark triggers this (I have a really slow machine). I don't really
understand the DEC scheme, so I'm wary of trying to debug it. Do you
guys have any ideas? You can see a screenshot here:
I didn't have a chance to view your screenshot before I closed down
for the night but I suspected this might be the case for you. This line
of code:
write_or_exit "${TS_POSITION}$(($SECONDS / 60)) min. $SEC sec. "
moves the cursor to the time printout region of the line (TS_POSITION)
and writes the minutes and seconds that have elapsed. The problem you
are seeing is character wraparound caused by the line length exceeding
80 chars.
Try this small change:
write_or_exit "${TS_POSITION}$(($SECONDS / 60)) min. $SEC sec"
and if it works for you, removing the trailing ". ", I will make the
change. (I could force 'no-wrap' on the terminal but that hides the
problem of line length)
The term 'Control Sequence Introducer' is/was Digital Equipment Corp's
(the originator of the VT100) fancy way of saying <ESC>[ . A full list
