What Aia suggested is fine if you're using a system where /bin/sh is not a pure Bourne shell (as it is on Solaris systems) or a 1988 Korn shell (as it is on many AIX systems). But, in addition to what Aia already commented on, there is nothing in your script that sets the shell variable _infos, so, unless that variable is being inherited from an exported variable in the environment of your script, the $_infos in your invocations of curl will be replaced by an empty string by the shell each time it invokes curl.

When posting questions to these forums, it always helps us provide answers that will work better in your environment if you tell us what operating system and shell you're using when you post questions. And, if you're using shell variables that aren't defined in your script, please tell us where those variables are being initialized.

If you are using a Solaris system or an AIX system or an HP/UX system, you're likely to get a bunch of syntax errors from Aia's suggestion, and we'll need to know which OS you're using, whether we can use a shell other than /bin/sh on your system (such as /usr/xpg4/bin/sh on a Solaris system or /bin/ksh93 on AIX) so we'll know if we can just use a different shell or if we need to convert the shell substring expansion into a single awk script (if you're stuck with a pure Bourne shell) or into POSIX conforming variable expansions in other shells.

atf-sh

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME

     atf-sh [-s shell] -- interpreter for shell-based test programs

SYNOPSIS

     atf-sh script

DESCRIPTION

     atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.

     atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL.  atf-sh executes the inter-
     preter, loads the atf-sh(3) library and then runs the script.  You must consider atf-sh to be a POSIX shell by default and thus should not
     use any non-standard extensions.

     The following options are available:

     -s shell	  Specifies the shell to use instead of the value provided by ATF_SHELL.

ENVIRONMENT

     ATF_LIBEXECDIR    Overrides the builtin directory where atf-sh is located.  Should not be overridden other than for testing purposes.
     ATF_PKGDATADIR    Overrides the builtin directory where libatf-sh.subr is located.  Should not be overridden other than for testing purposes.
     ATF_SHELL	       Path to the system shell to be used in the generated scripts.  Scripts must not rely on this variable being set to select a
		       specific interpreter.

EXAMPLES

     Scripts using atf-sh(3) should start with:

	   #! /usr/bin/env atf-sh

     Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh.  Instead, you have to hardcode
     the path to atf-sh in the script and then use the -s option afterwards as a single parameter:

	   #! /path/to/bin/atf-sh -s/bin/bash

ENVIRONMENT

     ATF_SHELL	  Path to the system shell to be used in the generated scripts.
