Awk; pattern match, remove and re write
the following pattern match works correctly for me

Code:
awk '/name="Fruits"/{f=1;next} /"name=Vegetables"/{f=0} f' filename


This works well for me. Id like to temporarily move the match out of the file ( > newfile) and be able to stick it back in the same place at a later time.

Is this possible?

not tested:
Code:
awk '
  FNR==NR { newf[++c]=$0; next }

/name="Fruits"/{f=1}
f && /"name=Vegetables"/ {
  for(i=1; i in newf; i++)
     print newf[i]
  f=0
}
1
' newfile filename > newNewFile

that is interested and I will certainly test. Follow up question if I may. What if I would like to put a place holder while the text is removed from the file. Perhaps a comment like


###
##--date was removed here

Code:
awk '
  FNR==NR { newf[++c]=$0; next }

/date was removed here/ {
  for(i=1; i in newf; i++)
     print newf[i]
  next
}
1
' newfile filename

You mean you want two output files - the "Fruits" file and the original file with the fruits - not the header "Fruits" - removed and the placeholder added?
If yes, you need to provide for this in your original code, and then you can use vgersh99's proposal to join the two files back.

is this a better explanation?


a. Match text between two patterns(including pattern)

b. Move match out to new file

c. Replace text in original file with comment (i.e. ##insert data here##)

d. Move back in to original file at same location at later date
