I wanted to remove certain pattern of contents based on a regex from csv file which is very large in size containing 100,000+ records, how is it possible via windows commandline? I also have sed and awk installed in my windows commandline
It hangs on opening in any spreadsheet processor or text editor(Including Notepad++).

Many of the editors mentioned support Regex search/replace. If you're determined to do it from the command-line, then what have you tried already? Did you try using
findstr? What were the results? – Ƭᴇcʜιᴇ007 – 2014-05-09T18:19:50.160I tried various editors , but I dont know about findstr – suuser – 2014-05-09T18:21:39.630
What have you tried with sed/awk? Have you tried the usual recommended editors like notepad++? – m4573r – 2014-05-09T18:51:55.640
@Ali - FINDSTR is a non-starter. It has crippled regex capability, it has many bugs, and it cannot replace content. – dbenham – 2014-05-09T19:45:19.820
I did try notepad++ but it crashes @m4573r – suuser – 2014-05-10T04:20:20.103
