I have the following data file:
Name: ABC
Address: 123, 4th Street,
My County,
10009 Country.
Age: 34
Gender: Male
Name: DEF
Address: 456, Orange Street,
North State,
45678 Country.
Age: 68
Gender: Female
Basically, each record is separated by 2 empty lines.
The problem is some "Address" will contain 2 empty lines too (see example above).
How can I replace the valid "2 empty lines" separator with say "#####", but leave the 2 empty lines in the "Address" field untouched (as is)?
Thanks.
I tried various "sed" commands with N options and "awk" commands, but nothing works so far :(
Assuming that each record ends with a Gender: line then you can do something like:
awk '{if(NR<=n)next;print $0}/Gender/{print"######";n=NR+2}' yourfile.txt

Let's say i have the following file:
balloons:
- 2
- 3
Each number above should represents how many times i want to print the string. So for example I would like to process this to output as following:
balloons:
- red
- red
- blue
- blue
- blue
I only have red and blue balloons. The digits will vary from one file to another, so my search string would be a simple regex search sed -e "/[[:digit:]]\+/ perform_my_action"
Try:
awk 'BEGIN{idx[2]="red"; idx[3]="blue"}
/^-[ \t]+[0-9]+/{for(i=1;i<=$2;i++) print idx[$2]; next}
1

I have a list of product codes grouped in 2 or 3 lines. I need to return the group where codes are not same (or consecutive)
9003103
9003103
9003978
9003979
9003763
9003728
9003543
9003543
9003543
In this case, only the third group should be returned:
9003763
9003728
I would harness GNU AWK for this task following way, let file.txt content be
9003103
9003103
9003978
9003979
9003763
9003728
9003543
9003543
9003543
then
awk 'BEGIN{RS=""}{diff=$NF-$1;diff=diff>0?diff:-diff}diff>NF' file.txt
gives output
9003763
9003728
Explanation: I set RS to empty string to provoke paragraph mode, thus every block is treated as single line, then for each block I compute absolute of difference between first and last field, if difference is bigger than number of field block is printed.
(tested in GNU Awk 5.0.1)

I.e., there is a header line which begins with a ">", and then an arbitrary number of lines with no more than 100 letters in them. I would like to find the positions within the non-header lines that match either "GCAGC" or "GCTGC". Overlapping match sites would both get recorded individually.
An example output would be a three column text file where the first column contained the header line for that block of text minus the ">", the second column contained the start position of a pattern match (i.e., the number of characters into the text block, excluding line-break characters), and the third column recorded which of the two patterns were matched. E.g.:
foo_bar 109 GCAGC
bar_foo 58289 GCTGC
Not sure how complex this task is, and in particular whether there is a memory-efficient way to perform this operation in a streaming fashion. awk or sed seem like two utilities which might work, but the required command is beyond my limited understanding of the programs.
A tiny tweak on yesterdays answer:
sub(/^>/,"") {
hdr = $0
next
}
{
while ( match($0,/GC[AT]GC/) ) {
print hdr, RSTART, substr($0,RSTART,RLENGTH)
$0 = substr($0,1,RSTART-1) " " substr($0,RSTART+1)
}
}
Please get the book Effective AWK Programming, 5th Edition, by Arnold Robbins to learn the basics of awk.

I am trying to do the following in my Bigquery sql:
input: myword1 myword my 3433123 other stuff
output: myword1 myword my
input: myword 23498780000123 more stuff
output: myword
I want the output shown above based on the above input.
I need everything before the numbers.
I tried using ^([\s\w\s]+)(?=[^\d\r\n]+\d+[^\d\r\n]+$) but re2 doesn't like it.
Re2 doesn't like ?= . Hope that helps
It seems like you want everything before the first digit. If so, you can use regexp_replace():
regexp_replace(mycol, '\s*\d.*$', '')

I am trying to replace the email prefix with the full first name using sed - drop the . and the initial and replace with the first name from the beginning of the line.
Antony Clark a.clark#zzz123.co ZZZ
Caroline Foster c.foster#zzz123.co ZZZ
Eg. a.clark#zzz123.co will become antony.clark#zzz123.co
thanks!
It's not glamorous, but awk with printf to preserve your formatting can be done as:
$ awk '{sub(/^[^.]+/,tolower($1),$3); printf "%-16s%-16s%-28s%s\n",$1,$2,$3,$4}' emails
Antony Clark antony.clark#zzz123.co ZZZ
Caroline Foster caroline.foster#zzz123.co ZZZ
If you simply want single space separated output, then that reduces to:
$ awk '{sub(/^[^.]+/,tolower($1),$3)}1' emails
Antony Clark antony.clark#zzz123.co ZZZ
Caroline Foster caroline.foster#zzz123.co ZZZ
(you can change the output field-separator to anything you desire)
Look things over and let me know if one of those will work.
