Question How to copy one file into another except some text
I have file input like-
Code:
abc,"123",""123","123","123","123","123","123","123","123","123","123","123","123",
abc,"123","123","123","123","123","123","123","123","123""123",abc etc

Input file consists of 1000 records and i want to copy into final file except abc
abc is at fixed position like 1,17,33,49 etc in short 1, (1+16) , (1+16+16) ,etc
How to do this, in efficient way using scripting??Smilie
Required output file:-
Code:
"123",""123","123","123","123","123","123","123","123","123","123","123","123"

sed -e 's/,abc/#/g' -e 's/abc,/#/g' -e 's/#//g' inputfile > outputfile

How to minimize the awk operation???
cat abc.csv | awk -F"," '{ print $1","$2","$3","$4","$5","$6","$7","$8","$9","$10","$11","$12","$13","$14","$15","$16", "$18","$17 }' > xyz.csv
i want to copy first 16 field and then 17,18 field.

See if this works for you :
Code:
awk 'BEGIN { FS=","; OFS="," } { printf $16","$17","$18; for (i=1;i<=15;i++) printf $i"," }' abc.csv | sed "s/,$//g" > xyz.csv

What is your record? How many fields in it? When you say about positions what do you mean?

How to minimize awk ?
Code:
cat abc.csv | awk -F"," '{ print  $1","$2","$3","$4","$5","$6","$7","$8","$9","$10","$11","$12","$13","$14","$15","$16",   "$18","$17 }' > xyz.csv

Input file: abc.csv contains 18 fields which are comma separated.
Output: xyz.csv file contains all those fields only difference in position of 17 and 18 such as 1,.....,16,17,18.
How to do in efficient way??
