Deleting part of a string enclosed in brackets
I use otool on OS X to figure out the shared libraries that a binary uses. I run this command:

otool -L /Applications/Vidnik\ 0.13.0/Vidnik.app/Contents/MacOS/Vidnik

And it returns an output similar to this:

Code:
/Applications/Vidnik 0.13.0/Vidnik.app/Contents/MacOS/Vidnik:
	/usr/lib/libcrypto.0.9.7.dylib (compatibility version 0.9.7, current version 0.9.7)
	/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 12.0.0)
	/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 677.15.0)
	/System/Library/Frameworks/QuickTime.framework/Versions/A/QuickTime (compatibility version 1.0.0, current version 67.0.0)
	/System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL (compatibility version 1.0.0, current version 1.0.0)
	/System/Library/Frameworks/AudioUnit.framework/Versions/A/AudioUnit (compatibility version 1.0.0, current version 1.0.0)
	/System/Library/Frameworks/QuartzCore.framework/Versions/A/QuartzCore (compatibility version 1.2.0, current version 1.5.1)
	/System/Library/Frameworks/QTKit.framework/Versions/A/QTKit (compatibility version 1.0.0, current version 1.0.0)
	/System/Library/Frameworks/Security.framework/Versions/A/Security (compatibility version 1.0.0, current version 33001.0.0)
	@executable_path/../Frameworks/Sparkle.framework/Versions/A/Sparkle (compatibility version 1.5.0, current version 1.5.0)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.0.0)
	/System/Library/Frameworks/CoreServices.framework/Versions/A/CoreServices (compatibility version 1.0.0, current version 32.0.0)
	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 227.0.0)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 476.10.0)
	/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit (compatibility version 45.0.0, current version 949.27.0)
	/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices (compatibility version 1.0.0, current version 34.0.0)

What I need to do is completely delete the first line of the output (this line: /Applications/Vidnik 0.13.0/Vidnik.app/Contents/MacOS/Vidnik:) and on each following line that lists a library, I need to delete the part in brackets (e.g. something like "(compatibility version x.x.x., current version, x.x.x)"). And then I need to delete any line that begins with "@executable_path". I know this is a long one, but I hope its possible

Any help would be appreciated

Thanks

See if this works.



Code:
 
 sed -e '1d' -e '/@executable_path/d'  filename | cut -d " " -f1

That worked brilliantly, thank you very much Smilie

awk can do the job alone Smilie
Code:
awk 'NR>1{print $1}' file

A small refinement, just one sed command is enough:
Code:
sed '1d; /@executable_path/d; s/\(^[^ ]*\) .*$/\1/' filename

Thanks everyone. The above command returns an output similar to this:

Code:
/usr/lib/libcrypto.0.9.7.dylib
/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa
/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation
/System/Library/Frameworks/QuickTime.framework/Versions/A/QuickTime
/System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL
/System/Library/Frameworks/AudioUnit.framework/Versions/A/AudioUnit
/System/Library/Frameworks/QuartzCore.framework/Versions/A/QuartzCore
/System/Library/Frameworks/QTKit.framework/Versions/A/QTKit
/System/Library/Frameworks/Security.framework/Versions/A/Security
/usr/lib/libgcc_s.1.dylib
/usr/lib/libSystem.B.dylib
/System/Library/Frameworks/CoreServices.framework/Versions/A/CoreServices
/usr/lib/libobjc.A.dylib
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation
/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit
/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices

Is it possible to make one further refinement to take out the part of each path that has "/Versions" in it. For example this:

/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit

Would become this:

/System/Library/Frameworks/AppKit.framework

Basically any part of a path that starts with "/Versions" is removed.

sed '1d; /@executable_path/d; s/\(^[^ ]*\) .*$/\1/; s/\(^[^ ]*\) .*$/\1/; s/\/Versions//' filename
