Utility to execute ELF binary directly from stdin pipe. It is useful to run binary via SSH without copy or install it on remote systems.

Run binary via ssh:

$ cat build-1234 | ssh user@host 'elfexec --test=integration --env=production'

Decode base64 encoded binary and run it directly:

$ echo 'IyEvYmluL3NoCmVjaG8gIkhlbGxvISIK' | base64 -d | elfexec

Compile source code and run it without temporary files:

$ echo '
#include <unistd.h>

int main(int argc, char* argv[])
{
    write(STDOUT_FILENO, "Hello!\n", 7);
    return 0;
}
' | cc -xc - -o /dev/stdout | elfexec

Require Linux 3.17 or higher:

• Precompiled static binaries built with system libc (glibc) and musl libc for x64 and i386
• From source code:

$ git clone https://github.com/abbat/elfexec.git
$ make && sudo make install

To compile with own flags use USER_CFLAGS and USER_LDFLAGS variables. For example for i386 static binary with musl libc:

$ CC=musl-gcc32 USER_CFLAGS=-m32 USER_LDFLAGS='-m32 -static -Wl,-melf_i386' make

elfexec [options]

Where options is executed binary options.

Executed binary exit code or 1 if self failed.
