[Bash] 'sleep' x becomes 'leep' x

xC0re · 05-26-2013, 11:59 AM

Hello,

I just started to write small scripts for my Kobo Mini.
At some points I need the script to pause for a few seconds.
So I used the sleep command.
Unfortunately the scripts don't work as they should.
After every 'sleep' command I get the error: 'leep: invalid number '
Independent of the number I use.
So 'sleep 2' --> 'leep: invalid number '
'sleep 10' --> 'leep: invalid number '

Any ideas how I can solve this Problem or another way to pause a script for a few seconds?

Thanks

Looks like something is eating the first letter of the command, maybe some uncommon character used for indentation?

xC0re · 05-26-2013, 02:23 PM

I didn't use any indentation.
One of the scripts looks like this.

Code:

#!/bin/sh 
sleep 10 
killall nickel 
killall hindenburg 
sleep 3 
crond & 
/bin/sh /mnt/onboard/update.sh

It's nearly in every script I wrote.
Astonishingly one script works. But only if its name ist update.sh.
If I rename the script but keep erverything else exactly the same, it throws also this error.

This is extremely strange. I have never seen such an error before.

Are these scripts being saved in Unix format (ie ending with only a linefeed) or DOS format (carriage return and linefeed)?

I've saved them with Kate on Kubuntu in Unix format.
Should I use the DOS format?

No... Unix format is perfect! Just wanted to make sure though.

The error is curious because it's not saying that it doesn't understand the command "leep" it's saying the number is invalid. I've checked on my Linux desktop and that's the same error I get out of busybox's sleep if I give it a non-numeric. So it seems the "s" is not being eaten so much as not displayed.

Doesn't explain why it's not accepting 3 and 10 as numbers though.

Just for information. sleep works on my touch.

------Problem solved------

I wrote a few different scripts for testing and I think I found the reason that some scripts don't work. Thanks @latepaul @PeterT for bringing me there

I transfered the scripts via Filezilla on my Kobo. Somehow through this transfer they seem to get messed up (I used auto detection instead of binary transfer. Maybe thats why).
If I log on via telnet on my Kobo and download the scripts via wget they work fine.

It might work with Filezilla in binary mode but at the moment everything works fine and I don't want to touch anything on the Kobo
