comparing contents of new files - numerical example
marsd, Sorry. Here's my example: file 1 ------ contains fields file1_field1 thru file1_field4 with numeric data (double-precision) as: file1_field1 file1_field2 file1_field3 file1_field4 16:00 10 20 30 16:10 40 50 60 16:20 12 23 14 file 2... -

comparing contents of two files (field comparison)
I want to write a script which will compare field(s) from two different files. The data in these fields is numeric and I want to identify the row number and data element where there is a match. I have sketched out some pseudo-code which may help explain my question; my explanations are denoted... -
reading in HH:MM:SS versus ignoring it (doing ops on HH,MM,SS)
Now that I am able to read in a file with HH:MM:SS values (the first element in each row), if I want to perform operations on the hours, minutes, and seconds, how do I read in hours, minutes, and seconds separately, while still reading in all of the other numeric fields in each row? For... -
Awk - reading in HH:MM:SS
This is another post of the same code I've posted before with a different slant and some more verbage below it: I'm attempting to run the following script from p.68 of the Aho, Kernighan, Weinberger bible: { for (i=1; i <=NF; i++) sum[i] += $i if (NF > maxfld) maxfld = NF } END { for (i = 1... -
Re-post (of Re-post) of Awk question Aho p. 77
Glanced over & saw "check" instead of "uncheck" - sorry. I am using all-numeric data, tab-delimited, as input to the following code from top of p.77; is there any reason that this script should not run as typed?: NR == 1 { nfld = NF for (i=1; i <=NF; i++) type[i] =... -
Re-post of Awk (Aho, ...) page 68 question
I am using all-numeric data, tab-delimited, as input to the following code: {for (i=1; i<=NF; i++) sum+=$i if(NF>maxfld) maxfld=NF } END {for (i=1; i<=maxfld; i++) { printf("%g",sum) if (i<maxfld) printf("\t") else printf("\n") } } According to the Aho, Kernighan... -
Re-post of Awk Data Processing Question
Trying to run the script in Section 3.2, page 77 of 'Data Validation' in the Aho, Kernighan, Weinberger book. I have a set of data that is 8-column numeric as input that will read in without any errors but I get no output. What is the problem? Should the code below run without error and if it... -
Data Processing in Awk
I am using all-numeric data, tab-delimited, as input to the following code: {for (i=1; i<=NF; i++) sum[i]+=$i if(NF>maxfld) maxfld=NF } END {for (i=1; i<=maxfld; i++) { printf("%g",sum[i]) if (i<maxfld) printf("\t") else printf("\n") } } According to the Aho... -
