Gsub regex not working
I have a number of files that I pass through awk/gsub. I believe to have found a working regex and on 'test bed' sites it matches, however within gsub it does not. Examples: Initial data: Code:
/Volumes/Daniel/Public/Drop Box/[sage]_Hellsing_Ultimate_OVA_-_10_[720p-AAC][4B4C84C5].mkv gsub & regex: Code:
gsub("\[[^\]]+\]",""I've been able to remove mostly everything with other expressions but the first brackets "[sage]" still remain. The content within the brackets varies a lot (e.g. [SFW-sage]. I'd like to keep the script as simple as possible (one line). |

One way to do it is using [ and ] as field separators is: Code:
awk -F '[]]|[[]' '{for(i=1; i<=NF; i+=2)printf("%s",$i);printf("\n")}' inor using gsub(): Code:
awk '{gsub("[[][^]]+[]]","")}1' inIf you're using a Solaris system, use /usr/xpg4/bin/awk or nawk instead of awk. Last edited by Don Cragun; 01-07-2013 at 10:32 PM.. Reason: provide two ways to do it |

awk gives me: Code:
awk: can't open file in source line number 1 nawk is unavailable. Edit: Your second solution works wonderfully. Thank you very much. Last edited by unknownn; 01-07-2013 at 10:43 PM.. |

You didn't say what the name was for the file that contains your "initial data". Both of the scripts I provided assume that the text you want to process is in a file named
in . I've tried both of them on Mac OS X Version 10.7.5. Since OS X is a Mac OS X system (not a Solaris system), use awk.
