replace two different strings with the nth line of a file every 2 nth occurrences of each string sep-CodePudding

I am trying to use the following command_line01 to replace the first and second occurrence of home_cool with the first line of 1.txt individually for each occurrence, and proceeding, replace the first and second occurrence of home_cool01 also by the first line of 1.txt individually, and then.., replace the third and fourth occurrences of home_cool with the second line of 1.txt individually., and etc, that is, every 2 nth occurrences of home_cool or home_cool01, respectively replace both strings with the nth line of 1.txt.

I tried command_line01 bellow:

awk 'NR==FNR {a[NR]=$0; next} /home_cool01/{gsub("home_cool01", a[  i<3])} /home_cool/{gsub("home_cool", a[  j<3])} 1' 1.txt 0.txt > 2.txt

but this only works for the first two occurrences for the next two occurrences home_cool or home_cool01 is replaced by nothing as show bellow:

"#sun\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag, tortoise,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag, tortoise,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree()\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree()\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag, tortoise,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag, tortoise,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree()\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree()\t",
"machine(shoes_shirt.shop)\t",

Here my two sources files:

0.txt:

"#sun\t",
"car_snif = house.group_tree(home_cool)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tre(home_cool)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool01)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool01)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool01)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool01)\t",
"machine(shoes_shirt.shop)\t",

and

1.txt:

(food, apple, sky, cat,blue,)(bag, tortoise,)
(food, apple, sky, cat,blue,)(bag,)
(food, apple, sky, cat,blue,)(bag, moon, tortoise,)

and my desire output 2.txt is:

"#sun\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag, tortoise,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag, tortoise,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag, tortoise,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag, tortoise,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag,))\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag,))\t",
"machine(shoes_shirt.shop)\t",

EDIT: from @markp-fuso comments:

1 - If there are multiple entries I would reboot from second if there is already finished processing the first entry.

2 - If I have more than 6 home_coool entries ... I continue from the beginning of 1.txt.

3 - I would like not to be limited to only two patterns of research, so it should be a proper solution when there is home_coool02, home_coool03 , ..., home_coool_some_sufix, but I need to keep an MWE as I posted initially

CodePudding user response：

Assumptions:

only need to worry about search patterns home_cool and home_cool01 (more can be added but will need a bit of rework; likely use an associative array to keep track of counts of each unique pattern)
replacement pattens are to be applied twice before moving on to the next replacement pattern
if we reach the end of the replacement patterns we start over from the beginning

Sample input:

$ cat 0.txt
"#sun\t",
"car_snif = house.group_tree(home_cool)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool01)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool01)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool01)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool01)\t",
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool)\t",          # pick up where we left off with 'home_cool'
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool)\t",          # restart from beginning of 0.txt replacment patterns
"machine(shoes_shirt.shop)\t",
"car_snif = house.group_tree(home_cool)\t",
"machine(shoes_shirt.shop)\t",

One awk idea:

awk '
NR==FNR       { a[NR]=$0; n=NR; next}
/home_cool01/ { gsub("home_cool01", a[int((i  )%(n*2)/2) 1])}
/home_cool/   { gsub("home_cool",   a[int((j  )%(n*2)/2) 1])}
1
' 1.txt 0.txt

Where:

n==3 - number of rows in 1.txt
%6 - will generate outputs of 0-5
(%6/2) - turns output into 0.0, 0.5, 1.0, 1.5, 2.0, 2.5
int(...) - turns output into 0, 0, 1, 1, 2, 2
1 - gives us our array indices of 1, 1, 2, 2, 3, 3
NOTE: yeah, a bit convoluted on the indexing; I'm open to suggestions to simplify

This generates:

"car_snif = house.group_tree((food, apple, sky, cat,blue,)(bag, tortoise,))\t",
