Subject: Dash only reads the first character from pipe (bash reads whole line)
Date: Sat, 14 Nov 2015 00:24:06 +0100	[thread overview]
Message-ID: <n25ren$pf5$1@ger.gmane.org> (raw)

Hello,

a 6 year old Debian bug [1] describes a problem with reading from pipes 
that is still present in the current dash version (I tested up to git 
commit 7062c78).

The following test, by the original reporter, shows the problem

 > The 'read' command seems to only read the first character and not the 
 > whole line.

 > Example / comparison with bash:

 > # /bin/dash
 > # sudo modprobe nf_conntrack
 > # read MAX </proc/sys/net/netfilter/nf_conntrack_max
 > # echo $MAX
 > 2
 >
 > # /bin/bash
 > # read MAX </proc/sys/net/netfilter/nf_conntrack_max
 > # echo $MAX
 > 262144

It this a known problem? Are there workarounds?

Regards,
