Top Forums UNIX for Dummies Questions & Answers Tcsh command for assigning output of awk to variable Post 302901962 by violin on Friday 16th of May 2014 04:50:30 PM

I tried the backticks--

mean=`awk '{ print $1}' data.txt`
echo $mean $id > mean.txt

but now it says
mean=0.067762: Command not found.
mean: Undefined variable.

also tried
set mean=`awk '{ print $1}' $roi.$sid.$task.1D`
echo $mean > mean.$sid.$task.1D

but get the same error.

thanks.

avc_context_to_sid(3)					     SELinux API documentation					     avc_context_to_sid(3)

NAME
avc_context_to_sid, avc_sid_to_context, avc_get_initial_sid - obtain and manipulate SELinux security ID's. SYNOPSIS
#include <selinux/selinux.h> #include <selinux/avc.h> int avc_context_to_sid(security_context_t ctx, security_id_t *sid); int avc_sid_to_context(security_id_t sid, security_context_t *ctx); int avc_get_initial_sid(const char *name, security_id_t *sid); DESCRIPTION
Security ID's (SID's) are opaque representations of security contexts, managed by the userspace AVC. avc_context_to_sid returns a SID for the given context in the memory referenced by sid. avc_sid_to_context returns a copy of the context represented by sid in the memory referenced by ctx. The user must free the copy with freecon(3). avc_get_initial_sid returns a SID for the kernel initial security identifier specified by name. RETURN VALUE
avc_context_to_sid and avc_sid_to_context return zero on success. On error, -1 is returned and errno is set appropriately. ERRORS
ENOMEM An attempt to allocate memory failed. NOTES
As of libselinux version 2.0.86, SID's are no longer reference counted. A SID will be valid from the time it is first obtained until the next call to avc_destroy(3). The sidget and sidput functions, formerly used to adjust the reference count, are no-ops and are deprecated. AUTHOR
