Hello,
I don’t know if it’s really a bug, if I’m just mistaken or this is the right address but I just want to give it a try.
I’m using the following bash-builtin printf command:
FUELLLAENGE=8 ; report="REPIBZVAG" ; REPORTFUELLZEICHEN="0" ; printf '%.8s%*.*d\n' $report 0 $((FUELLLAENGE - ${#report} )) "$REPORTFUELLZEICHEN"
The maximum length of $report is 8 characters but I tested some possible error situations so in this example it is 9 characters log. I would expect printf to cut the $report from REPIBVZAG to REPIBZVA and to NOT print
any additional trailing zeros because of the precision value of -1. But a trailing zero is printed (set –x output):
+ FUELLLAENGE=8
+ report=REPIBZVAG
+ REPORTFUELLZEICHEN=0
+ printf '%.8s%*.*d\n' REPIBZVAG 0 -1 0
REPIBZVA0
Is this really correct? Or shouldn’t the negative precision be taken as zero and no character should be printed?
The bash version is “GNU bash, version 3.2.51(1)-release (x86_64-suse-linux-gnu)”. I know it’s an older version but I can’t change it as there are corporate restrictions. The coreutil package is “coreutils-8.12-6.25.32.33.1”.
Best regards
