An ls alike command for listing/classifying aliases and bad aliases from a terminal prompt in OS X
The main objective is to provide the functionality below. The objective for sharing the code is to provide an easy acces point for people who want to make and share shell-tools that plays well with alias files on OS X.
Command line to compile: gcc -Os -I/System/Library/Frameworks/CoreFoundation.framework/Versions/A/Headers/ -o isalis isalis.m -lobjc -framework CoreFoundation -framework Cocoa
Enjoy.
Usage: isalis [options] [1..n file arguments or from stdin; one file on each line.]
All output options are mutually exclusive, the last one takes effect.
isalis [- -huncVdrvb]
isalis [ --help,--usage,--normal,--copyright --version,--delimiter,--report,--verbose,--broken ]
isalis file1 Returns the original item of file1 if it exists, great for the cd command.
cat flist |isalis prints the paths of the original items given from any aliases from stdin
cat flist |isalis -r Prints the original items of all aliases found, or broken, to the right of the filename.
cat flist | isalis -v Gives you a list of which files inspected, with aliases or BROKEN printed to the right of the inspected filename.
isalis --broken f1 f2 f3 f4 ... prints all broken aliases found in the files given on the command line.
-h,--help: Shows this help and quits.
-u,--usage: Shows this help and quits.
-n,--normal: Shows the alias if found in file-argument given. This is the same as giving no option.
-d,--delimiter: Sets the delimiter, for separating path and alias.
-c,--copyright: Prints out a copyright notice.
-V,--version: Prints out the version of isalis.
-r,--report: Prints a report containing every alias found in the file arguments, and if they are bad. Broken aliases are printed onto stderr.
