Bug#751347: grep: write error

[Francois Marier]

Adding "set +x" to the top of /usr/bin/rkhunter, here's where that error
comes from:

  + [ -n /usr/bin/lsof ]
  + FOUND=0
  + WHITEPROC=
  + BLACKPROC=
  + /usr/bin/lsof -wnlP +c 0
  + grep (dele
  + head -n 1
  grep: write error
  + DELE_FILES=git              4132           1000    2u      CHR              136,0      0t0          3 /dev/pts/0 (deleted)
  + [ -n git              4132           1000    2u      CHR              136,0      0t0          3 /dev/pts/0 (deleted) ]
  + PIDLIST=
  + get_option 2 multi ALLOWPROCDELFILE
  + OPTTYPE=2
  + OPTMULTI=multi
  + OPTV=ALLOWPROCDELFILE
  + grep -h ^ALLOWPROCDELFILE= /etc/rkhunter.conf /etc/rkhunter.conf.local

It looks like it comes from the optional PROCDEL module (which I have turned
ON). However, if I run the offending command manually:

  /usr/bin/lsof -wnlP +c 0 | grep '(dele' | head -n 1

that works just fine.

I don't know what that error even means. There's plenty of free space on all
of my disk partitions.
