UNIX for Dummies Questions & Answers

I have a script that produces two output files each containing the same number of lines <file1.txt> and <file2.txt>. What I need to do is combine both files into a new file <file3.txt> where line 1 of <file1.txt> is put to the right (and on the same line) as line 1 of <file2.txt> and then the same for the rest of the lines.

Then I need to add a comma to the end of every line EXCEPT the last line which needs a closing bracket.

Any advice / help would be appreciated.

Thanks

./pjg

look into 'man paste'

- paste the files with lines next to eachother
- put , at end of every line
- replace the , at end of last line with }

Then just redirect output with > file3

I hope that should be good.

Many thanks for both replies. If I wanted to seperate file1 and file2 with a | sign do I need to have this in file1 or file2 already or can it be added as part of the paste?

look into 'man paste'

-d, --delimiters=LIST
reuse characters from LIST instead of TABs

Thanks everyone for their help so far. I almost there but one thing has been causing me issues all day....

Code:

paste $prog $pan | sed "s/^/\'/" | sed 's/$/',/g' | sed '$s/,$/') with ur;/' > $progpan

The above is giving me 99% what I need. The only extra is getting a single quote mark ' to appear where I've marked in red.

Whatever I have tried with double quotes or backslashes has created a variety of errors.

Thanks

I've cracked it!
