There is no need to loop through the file with a bash loop. sed alone can handle it: $ sed -r '/^.{14}R.{12}D/s/(.{52}).{4}/\10000/' file 05196220141228R201412241308D201412200055SA1155WE130800001300SL07Y051 05196220141228R201412241308A201412220350SA0731SU1950LAX C00020202020 05196220141228R201412241308D201412200055SA1155WE130800005300SL07Y051 05196220141228N201412241308A201412240007TU0548WE1107MEL C00000000015 07054820141228N201412220850D201412180300TH1400MO085000040300UL180001 This uses the expression sed '/pattern/s/X/Y/' file:...
Sub-setting / Matching row and columns in R
This kind of magic is called matrix indexing. If you had rows and cols be the ones you didn't want, or if matrix indexing allowed for negative values, it would be even easier. y <- matrix(0, nrow=5, ncol=2) y[cbind(rows,cols)] <- x[cbind(rows,cols)] y ## [,1] [,2] ## [1,] 65 345 ##...

How to swap the lines in a file that match a condition using Shell script
unix,match,condition,swap,lines
Here is a simple Python script which implements what I think you are trying to describe. from sys import stdin keep = "A" kept = [] for line in stdin: line = line.rstrip("\r\n") pattern = line[27:28] # print("## keep %s, pattern %s, %s" % (keep, pattern, line)) if pattern !=...
Why is match returning the whole string as the first element in the array?
Zeroth element is always the full match. First element is the first capture, second element is the second capture, etc. If you just want all the captures without the full match, you can use result.slice(1). If you are asking "Why is the first element the full match?": It's just the...
INDEX/MATCH, or another function?

The "near miss" looks as though it used a helper column. Insert a ColumnC into Sheet3 and in C1 there enter: =A1&"|"&B1 Copy that down to suit. In your other sheet in ColumnP (Row1 ? - or adjust the N and O row references to suit) enter: =VLOOKUP($N1&"|"&$O1,Sheet3!$C:$F,2,0) and copy...

Use Python/Pandas to Match Sample Pairs Yearly Data
python,pandas,match,time-series,multi-index
This method is a little messy, but I am trying to make it more robust to account for missing data. First, we'll remove duplicates in the data and then convert the dates to Pandas Timestamps: df = df.drop_duplicates() df.SampleDate = [pd.Timestamp(ts) for ts in df.SampleDate] Then let's arrange you DataFrame...
Ruby Regex Replace Last Occurence of Grouping
If I correctly understood, you are interested in gsub with codeblock: str.gsub(PATTERN) { |mtch| puts mtch # the whole match puts $~[3] # the third group mtch.gsub($~[3], 'NEW') # the result } 'abc'.gsub(/(b)(c)/) { |m| m.gsub($~[2], 'd') } #⇒ "abd" Probably you should handle the case when there are no...
