awk

问题 I would like to search for a pattern in bunch of source files. The pattern should act as a marker. If the pattern is found, I would like to process that line by performing a substitution of another string For example: Private const String myTestString = @"VAL15"; // STRING—REPLACE-VAL## Here, I want to search my source file for pattern STRING—REPLACE-VAL and then replace VAL15 with VAL20 in same. Output: private const String myTestString = @"VAL20"; // STRING—REPLACE-VAL## Tried below command

问题 I want to write an awk script file using the #!/bin/awk -f header, but I want this script to always use : as a field separator. But for some reason writing #!/bin.awk -F: -f gives me a syntax error. I also want this script to always run on the same file, so I'd like to hardcode that as well. Basically, what I want to work is this: #!/bin/awk -F: -f -- /etc/passwd followed by some awk code 回答1: Something like this should do: #!/bin/awk -f # using the #!/bin/awk -f BEGIN { FS=":" # always use :

问题 I'm using some awk inside a bash script that's handling CSVs. The awk does this: ORIG_FILE="score_model.csv" NEW_FILE="updates/score_model.csv" awk -v d="2017_01" -F"," 'BEGIN {OFS = ","} {$(NF+1)=d; print}' $ORIG_FILE > $NEW_FILE Which does this transformation: # before model_description, type, effective_date, end_date Inc <= 40K, Retired, 08/05/2016, 07/31/2017 Inc > 40K Age <= 55 V5, Retired, 04/30/2016, 07/31/2017 Inc > 40K Age > 55 V5 , Retired, 04/30/2016, 07/31/2017 # after, bad model

问题 I wanted to compute some column differences in a csv file, say file: item1,0.01,0.1 item2,0.02,0.2 item3,0.03,0.3 expected output file: item1,0.01,0.1,-0.09 item2,0.02,0.2,-0.18 item3,0.03,0.3,-0.27 I tried something like this: awk -F, '{print $2-$3 "," $0}' and got the difference in the first column, but unable to put it in the 4th! The following didn't work and gave me strange result like: ',$0[original line]'. awk -F, '{print $0 "," $2-$3}' What's happening here? And how to fix this? I'm
