Hello,
Is there anyway that I can align a pipe delimited text file by the maxium field length where the field is separated out by pipes for large text files with more than
100,000 rows?
So, far I have searched other forums and google about aligning text files in unix and I have noticed that several other users use the awk utility. Since I am new to awk
I have attempted in writing my own code after reading some of the awk utility syntax, but I am getting stuck.
If awk is not the best utility to achieve this is there any way to code this???
My test code:
#!/bin/ksh
awk 'BEGIN {FS = "|"}
{
for(i=1;i<=NF;i++)
{
if (length($i) > max)
max = length($i)
maxlen($i) = max
}
}
END
{
for (i in max) print (i,max)
}
' $(find . -name "testfile.txt")
Below is a sample of the text file that I have:
Pipe Delimited Text file

Hi all,
I have a flat file of 1000 rows. I want to check the length of the 5th column. The one having the longest length , I want to set it as DEFINED PARAMETER.
So later I can check others with that particular number only.
Any ideas ?? (2 Replies)

hai guys,
pick the 1st field and calculate max length.
if suppose max length is 2,
then compare the all records if <2 then add zero's prefix of the record.
for ex:
s.no,sname
1,djud
37,jtuhe
in this max length of the 1st field is 2 right
the output wil be
s.no,sname
01,djud... (6 Replies)

HISTORY(5) File Formats Manual HISTORY(5)NAME
history - record of current and recently expired Usenet articles
DESCRIPTION
The file <pathdb in inn.conf>/history keeps a record of all articles currently stored in the news system, as well as those that have been
received but since expired. In a typical production environment, this file will be many megabytes.
The file consists of text lines. Each line corresponds to one article. The file is normally kept sorted in the order in which articles
are received, although this is not a requirement. Innd(8) appends a new line each time it files an article, and expire(8) builds a new
version of the file by removing old articles and purging old entries.
Each line consists of two or three fields separated by a tab, shown below as :
[Hash] date
[Hash] date token
The Hash field is the ASCII representation of the hash of the Message-ID header. This is directly used for the key of the dbz(3).
The date field consists of three sub-fields separated by a tilde. All sub-fields are the text representation of the number of seconds
since the epoch -- i.e., a time_t; see gettimeofday(2). The first sub-field is the article's arrival date. If copies of the article are
still present then the second sub-field is either the value of the article's Expires header, or a hyphen if no expiration date was speci-
fied. If an article has been expired then the second sub-field will be a hyphen. The third sub-field is the value of the article's Date
header, recording when the article was posted.
The token field is a token of the article. This field is empty if the article has been expired.
For example, an article whose Message-ID was <7q2saq$sal$1@isrv4.pa.vix.com>, posted on 26 Aug 1999 08:02:34 GMT and recieved at 26 Aug
1999 08:06:54 GMT, could have a history line (broken into three lines for display) like the following:
[E6184A5BC2898A35A3140B149DE91D5C]
935678987~-~935678821
@030154574F00000000000007CE3B000004BA@
In addition to the text file, there is a dbz(3) database associated with the file that uses the Message-ID field as a key to determine the
offset in the text file where the associated line begins. For historical reasons, the key includes the trailing byte (which is not
stored in the text file).
