The version of TextWrangler available in the Mac App Store does not support authenticated saves (the ability to save changes to files that you do not own) and does not include the command-line tools, in order to comply with Apple’s submission guidelines.
Authenticated saves are not possible in versions of TextWrangler obtained from the Mac App Store. If you desire this capability, please download TextWrangler directly from us.
Command-line tools: Any customer who has obtained TextWrangler from the Mac App Store may use the following package to install the command-line tools on their system. (This package is only for use with Mac App Store copies of TextWrangler, and is not suitable for use otherwise.)

TextWrangler 4 requires Mac OS X 10.6 or later (10.6.8, 10.7.5, 10.8.5, 10.9.5 or later recommended). It will not run on any earlier version of Mac OS X or on Mac OS 9.
You may encounter the following dialog when launching TextWrangler 4.5.3 or earlier on OS X 10.9 “Mavericks”:
This notification is due to an administrative change made by Apple in Mavericks and does not indicate any sort of error or problem.
You can prevent this issue by updating to TextWrangler 4.5.4 or later.
TextWrangler supports opening and editing files written in most left-to-right writing systems, including non-Roman languages such as Japanese, Chinese, and Korean.
However, TextWrangler does not support editing content in right-to-left languages such as Hebrew and Arabic. (You may also encounter inconsistencies when working with languages that routinely employ conjunct characters, such as Devanagari.)
Dealing with large files presents no intrinsic problems for TextWrangler. However, TextWrangler is a RAM-based editor, and it uses system memory to hold open files. TextWrangler also represents open documents as Unicode, which uses two bytes for each character. Combined with an internal Mac OS X limitation, this means that you can open files up to 384 megabytes in size (402,653,184 characters). To open a larger file, you will first need to split it into multiple parts, each less than 384M in size.
Just hold down the Option key (the mouse cursor will change to a cross shape) and then drag to make a rectangular selection.
Please note the “Soft Wrap Text” option must be turned off in order to make a rectangular selection. (You can turn off soft wrapping in the current document via the Text Options popup in the toolbar, or in the Text Options sheet.)
