While it is common to redirect stdout of pgrep to /dev/null, the better way is to close that file descriptor prior to call pgrep if only return code is needed. But (at least) pgrep does fail in such a case with error "pgrep: write error: Ungültiger Dateideskriptor" and return code of 1. Please make pgrep to not fail when there is no stdout (and/or stderr). - -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.5.7 (SMP w/8 CPU cores) Locale: LANG=de_DE, LC_CTYPE=de_DE (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages procps depends on: ii initscripts 2.88dsf-59.6 ii libc6 2.22-12 ii libncurses5 6.0+20160319-2 ii libncursesw5 6.0+20160319-2 ii libprocps5 2:3.3.11-3 ii libtinfo5 6.0+20160319-2 ii lsb-base 9.20160601 Versions of packages procps recommends: ii psmisc 22.21-2.1+b1 procps suggests no packages. - -- Configuration Files: /etc/sysctl.conf changed: net.ipv4.conf.default.rp_filter=1 net.ipv4.conf.all.rp_filter=1 net.ipv4.tcp_syncookies=1 net.ipv4.icmp_echo_ignore_broadcasts = 1 kernel.panic = 30 net.ipv4.tcp_ecn = 1 net.ipv4.tcp_fastopen = 1 - -- no debconf information - -- Klaus Ethgen http://www.ethgen.ch/ pub 4096R/4E20AF1C 2011-05-16 Klaus Ethgen <kl...@ethgen.ch> Fingerprint: 85D4 CA42 952C 949B 1753 62B3 79D0 B06F 4E20 AF1C -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 Comment: Charset: ISO-8859-1 iQGcBAEBCgAGBQJXaih0AAoJEKZ8CrGAGfas6DEL/0GSBtyN1S20K9q1N6E1qNS0 gjXw/TV8iB9y6PNUfEdpoHl+P7M1p+IBpASECnAI4b6rHVq9LKPvZvxRaSM+yRr4 sd9Tt3j0AUUM5iwNwkW4IZQwQi2TWzD5hhYXvSdSuKF8Txf70vj7+9UEXgj3di9w u8+NZ4L03w4juLAzs6NlaaD/2bq5OPonDuXBSRNwIcVlWR6Aao/PaVdmAC0ETpZN 8xLeNXEwXj8cl2U8Nb0rFdjjMnC+R+q2WFpefiHsPee0z0Mx1onqOTnklWDDC7ZB 9X5WX4/SU5vUV70ugXMhjPH6SBdHzdsxC6dIu1YG3J4KWnYg6OJcxZQtGiJwjI/B 9jSeQa4erNSQyd5HbjYPvCZiW8if+APpFygkOsTJ0S/+aDP+xe1q1JmqHFA2mgz2 f5xfIGm9VtQV+yDZqwUJnZqy9Preb1a00yBJ9yjTII7LHN7JOV5PC9p+0Xzo73lm z/2xjPYnQEciGg82KPRG4qsgTfwq3EcuqgXq7VBrcw== =dGg+ -----END PGP SIGNATURE-----
