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.

shcomp

SHCOMP(1)						    User Environment Utilities							 SHCOMP(1)

NAME

       shcomp - compile a ksh93 shell script

SYNOPSIS

       shcomp [ options ] [infile] [outfile]]

ORIGIN OF THIS MAN PAGE

       This man page was written by Christophe Martin <Schplurtz@free.fr> for the Debian GNU/Linux system. It is based on "shcomp --man" output.

DESCRIPTION

       Unless  -D  is  specified,  shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh93 can read and execute
       with the same effect as the original script.

       Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly.

       If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages	that  need  to	be  translated	to
       locale specific versions for internationalization.

       If  outfile is omitted, then the results will be written to standard output.  If infile is also omitted, the shell script will be read from
       standard input.

OPTIONS

       -D, --dictionary
	      Generate a list of strings that need to be placed in a message catalog for internationalization.

       -n, --noexec
	      Displays warning messages for obsolete or non-conforming constructs.

       -v, --verbose
	      Displays input from infile onto standard error as it reads it.

       --man  Displays this man page on standard error and exits.

       --help Shows a short help message and exits.

EXIT STATUS

       0      Successful completion.

       >0     An error occurred.

DEBIAN WARNING

       On a Debian GNU/Linux system, more than one package may provide ksh. the output of shcomp can only be used by ksh93.  Any other ksh will be
       unable to run the compiled script.

EXAMPLE

       ( echo '#! /bin/ksh93' ; shcomp myscript ) > myscript.bin &&
       chmod 755 myscript.bin
       ./myscript.bin
