Top Forums UNIX for Dummies Questions & Answers String manipulation for sheer speed... Post 302813225 by alister on Sunday 26th of May 2013 08:10:05 PM

bash has a well-deserved reputation for being slow. A few years ago, its poor performance led Ubuntu Linux to abandon it for boot scripts (although bash remains the default interactive login shell for users).

If you aren't wedded to bash, and if the scripts in question aren't brimming with bashisms, you could try running them under ksh (which was installed by default on OS X when I last used the OS, a few years ago).

NAME
install_name_tool - change dynamic shared library install names SYNOPSIS
install_name_tool [-change old new ] ... [-rpath old new ] ... [-add_rpath new ] ... [-delete_rpath new ] ... [-id name] file DESCRIPTION
Install_name_tool changes the dynamic shared library install names and or adds, changes or deletes the rpaths recorded in a Mach-O binary. For this tool to work when the install names or rpaths are larger the binary should be built with the ld(1) -headerpad_max_install_names option. -change old new Changes the dependent shared library install name old to new in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary does not contain the old install name in a specified -change option the option is ignored. -id name Changes the shared library identification name of a dynamic shared library to name. If the Mach-O binary is not a dynamic shared library and the -id option is specified it is ignored. -rpath old new Changes the rpath path name old to new in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary does not contain the old rpath path name in a specified -rpath it is an error. -add_rpath new Adds the rpath path name new in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary already contains the new rpath path name specified in -add_rpath it is an error. -delete_rpath old deletes the rpath path name old in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary does not contains the old rpath path name specified in -delete_rpath it is an error. SEE ALSO
