That would be because your grep command isn't actually executed, but is a plain string, which is always true. Lose the test command and the quotes, as test is only needed when you're doing a comparison, but not when the command returns a true or false exit code.

Hi there,
I'm very used to use set -e to break my scripts if any command exits with a non-zero status.
As a policy, I'm willingly expecting echo hello | grep a to break the script.
The commands test 1 -eq $1 && echo hello exits with a non-zero status if $1 is not 1. BUT... It doesn't break... (2 Replies)

glgenframebuffers
GLGENFRAMEBUFFERS(3G) [FIXME: manual] GLGENFRAMEBUFFERS(3G)
NAME
glGenFramebuffers - generate framebuffer object names
C SPECIFICATION
void glGenFramebuffers(GLsizei n, GLuint *ids);
PARAMETERS
n
Specifies the number of framebuffer object names to generate.
ids
Specifies an array in which the generated framebuffer object names are stored.
DESCRIPTION
glGenFramebuffers returns n framebuffer object names in ids. There is no guarantee that the names form a contiguous set of integers;
however, it is guaranteed that none of the returned names was in use immediately before the call to glGenFramebuffers.
Framebuffer object names returned by a call to glGenFramebuffers are not returned by subsequent calls, unless they are first deleted with
glDeleteFramebuffers().
The names returned in ids are marked as used, for the purposes of glGenFramebuffers only, but they acquire state and type only when they
are first bound.
ERRORS
GL_INVALID_VALUE is generated if n is negative.
SEE ALSO
glBindFramebuffer(), glDeleteFramebuffers()
