Replacing Multiple spaces with a single space but excluding few regular expressions
Hi All.
Attached are two files.
I ran a query and have the output as in the file with name "FILEWITHFOURRECORDS.txt "
I didn't want all the spaces between the columns so I squeezed the spaces with the "tr" command and also added a carriage return at the end of every line.
But in two columns I.e., the second and third column, I have a description where it has spaces in between and it should NOT be removed. But as I apply a 'tr' on the whole file, even those spaces are removed.
Could you please help me, how to retain the spaces in that string and replace everything else.
There are no double quotes in FILEWITHFOURRECORDS.txt, so how did your code generate them? Without any separators/tokens/indicators, how can we tell where $2 stops and $3 starts?

or do field2 and 3 always have five comma separated elements?
My bad, That result was from a query which I executed before, but the 2nd and 3rd fields does have the quotes around it.
And to your questions $2 and $3 have four or sometimes five comma separated elements
My bad, That result was from a query which I executed before, but the 2nd and 3rd fields does have the quotes around it.
And to your questions $2 and $3 have four or sometimes five comma separated elements
So, your real data contains double quotes surrounding fields 2 and 3, but the sample data you've shown us contains no double quotes? And, without the quotes fields 2 and 3 sometimes contain 3 commas and sometimes contain 4 commas. So how are we supposed to guess where to add the double quotes?
I am confused.
Can you please show us the output from your query that contains the double quotes and show us the output you hope to produce from that output? (Please post samples in-line in a post (in CODE tags) if at all possible instead of uploading files that everyone who wants to help you has to download.)

I am trying to read a txt file and trying to translate multiples spaces into single spaces so the file is more organized, but whenever I try the command:
tr ' ' ' ' w.txt
The output is:

Try `tr --help' for more information.
Can someone please help? :wall:
