I have text:

Fishing tour.png
Fishing tour2.png
One Day Tour.png
Sydney Adventure 3 Days Package.png
Sydney Northern Beaches Scenic Flight by Seaplane.png
Week trip.png
Weekend trip to Baku.png
Fishing tour a0HR000000B4wMUMAZ    
One Day Tour a0HR000000B4wMVMAZ    
Sydney Adventure 3 Days Package a0HR000000B4wMWMAZ    
Sydney Northern Beaches Scenic Flight by Seaplane a0HR000000B4wSuMAJ   
Week trip a0HR000000B4wMTMA    
Weekend trip to Baku a0HR000000B4wMSMAZ

I want to make two conditions.

1. Replace identical words without extension by words with extension, can be any extension ('Fishing tour' replace on 'Fishing tour.png') and remain Id as it is.
2. Words with appended number(0-9) put on new line with id matching to previous word identical to it ('Fishing tour' replace on 'Fishing tour2.png' and remain id of 'Fishing tour', so this id happens twice in text).

So, desired output should be:

Fishing tour.png a0HR000000B4wMUMAZ   
Fishing tour2.png a0HR000000B4wMUMAZ(id is identical as on the line above)    
One Day Tour.png a0HR000000B4wMVMAZ    
Sydney Adventure 3 Days Package.png a0HR000000B4wMWMAZ    
Sydney Northern Beaches Scenic Flight by Seaplane.png a0HR000000B4wSuMAJ    
Week trip.png a0HR000000B4wMTMAZ   
Weekend trip to Baku.png a0HR000000B4wMSMAZ

Please, help If someone know how to do this using awk or sed or any other tool that's available in Bash.

My code attempt:

sed -E 's/(. ([0-9])?\.. )|. [[:space:]]([a-zA-Z0-9] )/\1\3/g'

CodePudding user response：

$ cat tst.awk
{
    if ( match($0,/[0-9]*\.[^.]  *$/) ) {
        key = substr($0,1,RSTART-1)
        vals[key,  numVals[key]] = $0
    }
    else {
        key = $0
        sub(/  [^ ]  *$/,"",key)
        ids[key] = $NF
    }
}
END {
    for ( key in ids ) {
        for ( i=1; i<=numVals[key]; i   ) {
            print vals[key,i], ids[key]
        }
    }
}

$ awk -f tst.awk file
Weekend trip to Baku.png a0HR000000B4wMSMAZ
Fishing tour.png a0HR000000B4wMUMAZ

If the output order matters it's an easy tweak.

The above assumes that all of the key values can fit in memory.
