I need to search for a key and append the value to every key:value pair in a Unix file
Input file data:
1A:trans_ref_id|10:account_no|20:cust_name|30:trans_amt|40:addr
1A:trans_ref_id|10A:ccard_no|20:cust_name|30:trans_amt|40:addr
My desired Output:
account_no|1A:trans_ref_id
account_no|10:account_no
account_no|20:cust_name
account_no|30:trans_amt
account_no|40:addr
ccard_no|1A:trans_ref_id
ccard_no|10A:ccard_no
ccard_no|20:cust_name
ccard_no|30:trans_amt
ccard_no|40:addr
Basically, I need the value of 10 or 10A appended to every key:value pair and split into new lines. To be clear, this won't always be the second field.
I am new to sed, awk and perl. I started with extracting the value using awk:
awk -v FS="|" -v key="59" '$2 == key {print $2}' target.txt
I need the value of 10 or 10A appended to every key:value pair
Going by these requirements, you may try this awk:
awk '
BEGIN{FS=OFS="|"}
match($0, /\|10A?:[^|]+/) {
s = substr($0, RSTART, RLENGTH)
sub(/.*:/, "", s)
}
{
for (i=1; i<=NF; ++i)
print s, $i
}' file
account_no|1A:trans_ref_id
account_no|10:account_no
account_no|20:cust_name
account_no|30:trans_amt
account_no|40:addr
ccard_no|1A:trans_ref_id
ccard_no|10A:ccard_no
ccard_no|20:cust_name
ccard_no|30:trans_amt
ccard_no|40:addr
# Looks for 10 or 10A
perl -F'\|' -lane'my ($id) = map /^10A?:(.*)/s, #F; print "$id|$_" for #F'
# Looks for 10 or 10<non-digit><maybe more>
perl -F'\|' -lane'my ($id) = map /^10(?:\D[^:]*)?:(.*)/s, #F; print "$id|$_" for #F'
-n executes the program for each line of input.
-l removes LF on read and adds it on print.
-a splits the line on | (specified by -F) into #F.
The first statement extracts what follows : in the field with id 10 or 10-plus-something.
The second statement prints a line for each field.
Specifying file to process to Perl one-liner
If you are still stuck on where to get started, you will use a field-separator and output-field-separator (FS and OFS) set equal to '|' that will split each record into fields at each '|'. Your fields are available as $1, $2, ... $NF. You care about getting, e.g. account_no from field two ($2) so you split() field two with the separator ':' saving the split fields in an array (a used below). You want the second part from field two which will be in the 2nd array element a[2] to use as the new field-1 in output.
The rest is just looping over each field and outputting a[2] a separator and then the current field. You can do that with:
awk 'BEGIN{FS=OFS="|"} {split ($2,a,":"); for(i=1;i<=NF;i++) print a[2],$i}' file
Example Use/Output
With your example input in file, the result would be:
account_no|1A:trans_ref_id
account_no|10:account_no
account_no|20:cust_name
account_no|30:trans_amt
account_no|40:addr
ccard_no|1A:trans_ref_id
ccard_no|10A:ccard_no
ccard_no|20:cust_name
ccard_no|30:trans_amt
ccard_no|40:addr
Which appears to be what you are after. Let me know if you have further questions.
"10" or "10A" at Unknown Field
You can handle the fields containing "10" and "10A" in any order. You just add a loop to loop over the fields and determine which holds "10" or "10A" and save the 2nd element from the array resulting from split() from that field. The rest is the same, e.g.
awk '
BEGIN { FS=OFS="|" }
{ for (i=1;i<=NF;i++){
split ($i,a,":")
if (a[1]=="10"||a[1]=="10A"){
key=a[2]
break
}
}
for (i=1;i<=NF;i++)
print key, $i
}
' file1
Example Input
1A:trans_ref_id|10:account_no|20:cust_name|30:trans_amt|40:addr
1A:trans_ref_id|20:cust_name|30:trans_amt|10A:ccard_no|40:addr
Example Use/Output
awk '
> BEGIN { FS=OFS="|" }
> { for (i=1;i<=NF;i++){
> split ($i,a,":")
> if (a[1]=="10"||a[1]=="10A"){
> key=a[2]
> break
> }
> }
> for (i=1;i<=NF;i++)
> print key, $i
> }
> ' file1
account_no|1A:trans_ref_id
account_no|10:account_no
account_no|20:cust_name
account_no|30:trans_amt
account_no|40:addr
ccard_no|1A:trans_ref_id
ccard_no|20:cust_name
ccard_no|30:trans_amt
ccard_no|10A:ccard_no
ccard_no|40:addr
Which picks up the proper new field 1 for output from the 4th field containing "10A" for the second line above.
Let em know if this is what you needed.
EDIT: To find 10 OR 10A values in anywhere in line and then print as per that try following then.
awk '
BEGIN{
FS=OFS="|"
}
match($0,/(10|10A):[^|]*/){
split(substr($0,RSTART,RLENGTH),arr,":")
}
{
for(i=1;i<=NF;i++){
print arr[2],$i
}
}' Input_file
Explanation: Adding detailed explanation for above.
awk ' ##Starting awk program from here.
BEGIN{ ##Starting BEGIN section of this program.
FS=OFS="|" ##Setting FS and OFS to | here.
}
match($0,/(10|10A):[^|]*/){ ##using match function to match either 10: till | OR 10A: till | here.
split(substr($0,RSTART,RLENGTH),arr,":") ##Splitting matched sub string into array arr with delmiter of : here.
}
{
for(i=1;i<=NF;i++){ ##Running for loop for each field for each line.
print arr[2],$i ##Printing 2nd element of ar, along with current field.
}
}' Input_file ##Mentioning Input_file name here.
With your shown samples, please try following.
awk '
BEGIN{
FS=OFS="|"
}
{
split($2,arr,":")
print arr[2],$1
for(i=2;i<=NF;i++){
print arr[2],$i
}
}

Here's an alternate perl solution:
perl -pe '($id) = /(?<![^|])10A?:([^|]+)/; s/([^|]+)[|\n]/$id|$1\n/g'
($id) = /(?<![^|])10A?:([^|]+)/ this will capture the string after 10: or 10A: and save in $id variable. First such match in the line will be captured.
s/([^|]+)[|\n]/$id|$1\n/g every field is then prefixed with value in $id and | character
I have a radius log file which is comma separated.

Is it possible through any Linux command line tool like awk to count the number of occurrences where the second column (the time) and the seventh column (the number) are the same, and a Start event follows a Stop event?
I want to find the occurrences where a Stop is followed by a Start at the same time for the same number.
There will be other entries as well with the same timestamp between these cases.
You don't say very clearly what kind of result you want, but you should use Perl with Text::CSV to process CSV files.
This program just prints the three relevant fields from all lines of the file where the event is Start or Stop and the time and the ID string are duplicated.
use strict;
use warnings;
use Text::CSV;
my $csv = Text::CSV->new;
open my $fh, '<', 'text.csv' or die $!;
my %data;
while (my $row = $csv->getline($fh)) {
my ($time, $event, $id) = #$row[1,3,6];
next unless $event eq 'Start' or $event eq 'Stop';
push #{ $data{"$time/$id"} }, $row;
}
for my $lines (values %data) {
next unless #$lines > 1;
print "#{$_}[1,3,6]\n" for #$lines;
print "\n";
}
output
00:52:23 Stop 15444111111
00:52:23 Start 15444111111
I have tried the following using GNU sed & awk
sed -n '/Stop/,/Start/{/Stop/{h};/Start/{H;x;p}}' text.csv \
| awk -F, 'NR%2 != 0 {prev=$0;time=$2;num=$7} \
NR%2 == 0 {if($2==time && $7==num){print prev,"\n", $0}}'
The sed part would select pairing Stop line and Start line. There can(or not) be other lines between the two lines, and if there are multiple Stop lines before a Start line the last Stop line would be selected (This may be not necessary in this case...).
The awk part would compare the selected pairs in sed part, if the second and seventh columns are identical, the pair would be print out.
My test as below:
text.csv:

If the "stop" line is followed immediately by the "start" line, you could try the following:
awk -f cnt.awk input.txt
where cnt.awk is
BEGIN {
FS=","
}
$4=="\"Stop\"" {
key=($2 $5)
startl=$0
getline
if ($4=="\"Start\"") {
if (key==($2 $5)) {
print startl
print $0
}
}
}
Update
If there can be other lines between a "Start" and "Stop" line, you could try:
BEGIN {
FS=","
}
$4=="\"Stop\"" {
a[($2 $5)]=$0
next
}
$4=="\"Start\"" {
key=($2 $5)
if (key in a) {
sl[++i]=a[key]
el[i]=$0
}
}
END {
nn=i
for (i=1; i<=nn; i++) {
print sl[i]
print el[i]
}
}
