Package: dash
Version: 0.5.5.1-7.3
Severity: important
But, for word splitting, it shouldn't matter. Bash works as expected.
I flagged this "Severity: important" because this can potentially break a
lot of scripts.
Here is an example. The initial idea was to filter the list produced by
ip and pick up only the interfaces flagged LOWER_UP.
---8<---
#!/bin/dash
set -e
set -u
#set -x
IFS=': '
ip -o link show | while read n i s rest; do
echo n="|$n|", i="|$i|", s="|$s|", rest="|$rest|" >&2
done
--->8---
The unexpected output from the above is:
n=|2|, i=||, s=|eth0|, rest=| <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
pfifo_fast state UP qlen 100 link/ether 00:13:20:b0:fd:f6 brd
ff:ff:ff:ff:ff:ff|
$i, the interface name is shifted to the next variable $s.
After swapping the IFS characters (IFS=' :'), I get the expected output:
n=|2|, i=|eth0|, s=|<BROADCAST,MULTICAST,UP,LOWER_UP>|, rest=|mtu 1500 qdisc
pfifo_fast state UP qlen 100 link/ether 00:13:20:b0:fd:f6 brd
ff:ff:ff:ff:ff:ff|
Thoughts?
