As can be seen in the Code Snippet, line number 2 should be part of line number 1, but there is a line break splitting the transaction into two lines. The requirement is following.

How can this be done in already generated file ? There are thousands of similar lines in the cdr file which needs to corrected .TIA

Answer 2

Would you please try the following:

awk '
/^[[:digit:]]{4}-[[:digit:]]{2}-[[:digit:]]{2}/ {       # if the record starts with a date
    if (line) print line                                # flush the line buffer
    line = ""
}
{
    line = line $0                                      # append the current record to the line buffer
}
END {
    if (line) print line                                # flush the line buffer at the end of the file
}
' file.txt

Output with the provided example:

I assume that each row should have 37 columns.

Answer 4

This might work for you (GNU sed):

sed ':a;N;/\n....-..-.. ..:..:..,/!s/\n//;ta;P;D' file

Open a 2 line window in the pattern space.

If the second line does not begin with a date and time, remove the newline (append line 2 to line 1), append the next line and repeat until failure.

Print/delete the first of the two lines and repeat.
