You don't say what operating system or shell this is using. I'm going to guess some distro of Linux and the Bash shell...

Check the filenames that your wildcard expands to. It's likely there's a character in there that when expanded in the gdb command line is giving the shell some grief.

Some rules for typing in shell commands:

1. Always put double quotes around your dollar-sign variables. (It's only wrong about 3 times in 1,000 so you've got a 99.7% chance of being right. Smilie)

2. Use $(...) instead of `...`. (Won't matter in this particular case, but it's a good idea for a variety of reasons.)

3. Don't use a bunch of pipes when they're not necessary. (In this case using gdb is way overkill as the file command will likely give you the right data. Using a command like set -- $(file "$i") eliminates all of the pipes and only requires a single fork/exec because the set command is builtin to the shell.)

Otherwise I agree with TonyFullerMalv; you need to go back to basics and test out each piece of your command line. In particular, you need to know what data is going into the loop (such as the filenames).

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME
platform::shell - System identification support code and utilities SYNOPSIS
package require platform::shell ?1.1.4? platform::shell::generic shell platform::shell::identify shell platform::shell::platform shell _________________________________________________________________ DESCRIPTION
The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell. This package allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only requirement is that the other shell (identified by its path), is actually executable on the current machine. While for most platform this means that the architecture of the interrogated shell is identical to the architecture of the running shell this is not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run 32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers. For applications like a code repository it is important to identify the architecture of the shell which will actually run the installed packages, versus the architecture of the shell running the repository software. COMMANDS
platform::shell::identify shell This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell. platform::shell::generic shell This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell. platform::shell::platform shell This command returns the contents of tcl_platform(platform) for the specified Tcl shell. KEYWORDS
operating system, cpu architecture, platform, architecture platform::shell 1.1.4 platform::shell(n)
