I have a file with three fields and field delimiter '|' like:
In the file the 1st line has proper data -> abc|12:13:45|123
,the 2nd line doesnt has data for the 3rd field which is okay
, the 3rd line doesnt has data for the 3rd field as well the field delimiter before the 3rd field is also missing.
I have the requirement to add the field delimiter for the last field if the last field as well as the field delimiter is missing as with the case of the 3rd line:
the 3rd line should look like:
Please help me in this?

I have file with 20 fields and its pipe delimiter. I need to remove the 18th field along with pipe delimiter that seperates 17th and 18th field. In turn that means i want to make it now a file with only 19 fields. Can some body let me know how ican remove the 18th field from the whole file? (5 Replies)

The typical line of the input file is as follows,
123|abcde|"xyz|mn"|ghelosa|3455hello|
The delimiter is |. I need to change it to another delimiter, say ~. For the above line, the output should be:

The challenge is when | appears in a field, it... (2 Replies)

join
JOIN(1) BSD General Commands Manual JOIN(1)NAME
join -- relational database operator
SYNOPSIS
join [-a file_number | -v file_number] [-e string] [-o list] [-t char] [-1 field] [-2 field] file1 file2
DESCRIPTION
The join utility performs an ``equality join'' on the specified files and writes the result to the standard output. The ``join field'' is
the field in each file by which the files are compared. The first field in each line is used by default. There is one line in the output
for each pair of lines in file1 and file2 which have identical join fields. Each output line consists of the join field, the remaining
fields from file1 and then the remaining fields from file2.
The default field separators are tab and space characters. In this case, multiple tabs and spaces count as a single field separator, and
leading tabs and spaces are ignored. The default output field separator is a single space character.
Many of the options use file and field numbers. Both file numbers and field numbers are 1 based, i.e., the first file on the command line is
file number 1 and the first field is field number 1. The following options are available:
-a file_number
In addition to the default output, produce a line for each unpairable line in file file_number.
-e string
Replace empty output fields with string.
-o list
The -o option specifies the fields that will be output from each file for each line with matching join fields. Each element of list
has the either the form 'file_number.field', where file_number is a file number and field is a field number, or the form '0' (zero),
representing the join field. The elements of list must be either comma (',') or whitespace separated. (The latter requires quoting
to protect it from the shell, or, a simpler approach is to use multiple -o options.)
-t char
Use character char as a field delimiter for both input and output. Every occurrence of char in a line is significant.
-v file_number
Do not display the default output, but display a line for each unpairable line in file file_number. The options -v 1 and -v 2 may be
specified at the same time.
-1 field
Join on the field'th field of file 1.
-2 field
Join on the field'th field of file 2.
When the default field delimiter characters are used, the files to be joined should be ordered in the collating sequence of sort(1), using
the -b option, on the fields on which they are to be joined, otherwise join may not report all field matches. When the field delimiter char-
acters are specified by the -t option, the collating sequence should be the same as sort(1) without the -b option.
If one of the arguments file1 or file2 is ``-'', the standard input is used.
EXIT STATUS
The join utility exits 0 on success, and >0 if an error occurs.
COMPATIBILITY
For compatibility with historic versions of join, the following options are available:
-a In addition to the default output, produce a line for each unpairable line in both file 1 and file 2.
-j1 field
Join on the field'th field of file 1.
-j2 field
Join on the field'th field of file 2.
-j field
Join on the field'th field of both file 1 and file 2.
-o list ...
Historical implementations of join permitted multiple arguments to the -o option. These arguments were of the form
'file_number.field_number' as described for the current -o option. This has obvious difficulties in the presence of files named
'1.2'.
These options are available only so historic shell scripts do not require modification. They should not be used in new code.
LEGACY DESCRIPTION
The -e option causes a specified string to be substituted into empty fields, even if they are in the middle of a line. In legacy mode, the
substitution only takes place at the end of a line.
Only documented options are allowed. In legacy mode, some obsolete options are re-written into current options.
For more information about legacy mode, see compat(5).

The join command conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
