A better way to compare text length percentage? Post 303046101 by bedtime on Thursday 23rd of April 2020 07:52:48 PM

Thank you all for you solutions. I ended up going with vegersh99's solution as it was the most brief. I liked RudiC's mathmatics with the inverse equation.

Since I cannot have 'division by zero' errors, I added the 'if' statement near the end. Found out that shell doesn't like to compare numbers with decimals so added the int() function as well:

Would really like to figure out how to get this to do the equation so as not to have the 'division by zero' error when one or two variables have an empty string. I've tried a bunch of things such as adding '1' to each variable and trying to make it up elsewhere, but each time the values are incorrect.

Anyways, for now, it's more concise, and it's being used in the code.

Thanks everyone!

## How to Compare two files depend on line length Chars

I need to compare two files with exactly same length as example: - File1 contain 500 records with length of 640 chars of each line. File2 contain 1500 records with length of 640 chars of each line. I need get an output to be written in File3 which will contain 1000 records difference. but...

## Need awk script to compare 2 fields in fixed length file.

Need a script that manipulates a fixed length file that will compare 2 fields in that file and if they are equal write that line to a new file. i.e. If fields 87-93 = fields 119-125, then write the entire line to a new file. Do this for every line in the file. After we get only the fields...

## compare 2 very large lists of different length

I have two very large datasets (>100MB) in a simple vertical list format. They are of different size and with different order and formatting (e.g. whitespace and some other minor cruft that would thwart easy regex). Let's call them set1 and set2. I want to check set2 to see if it contains...

## changing a variable length text to a fixed length

Hi, Can anyone help with a effective solution ? I need to change a variable length text field (between 1 - 18 characters) to a fixed length text of 18 characters with the unused portion, at the end, filled with spaces. The text field is actually field 10 of a .csv file however I could cut...

## Aligning text files by max field length

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...

## print variable length text from the middle of a line?

I am trying to get text from a webpage, in terminal form. So far I am: 1. getting the html for the page printed using curl (curl -s webpage.com), which is then 2. piped to awk, printing line number 29 (awk NR==29), then 3. this is where I am sort of lost. I know where in the printed line I...

## awk to output the percentage of a field compared to length

The awk below using the sample input would output the following: Basically, it averages the text in \$5 that matches if \$7 < 30 . awk '{if(len==0){last=\$5;total=\$7;len=1;getline}if(\$5!=last){printf("%s\t%f\n", last,...

```wc(1)							      General Commands Manual							     wc(1)

NAME
wc - Counts the lines, words, characters, and bytes in a file

SYNOPSIS
wc [-c  | -m] [-lw] [file...]

The  wc	command  counts the lines, words, and characters or bytes in a file, or in the standard input if you do not specify any files, and
writes the results to standard output. It also keeps a total count for all named files.

STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:

wc:  XCU5.0

OPTIONS
Counts bytes in the input.  Counts lines in the input.  Counts characters in the input.	Counts words in the input.

OPERANDS
Specifies the pathname of the input file.  If this operand is omitted, standard input is used.

DESCRIPTION
A word is defined as a string of characters delimited by white space as defined in the X/Open Base Definitions for XCU4.

The wc command counts lines, words, and bytes by default.  Use the appropriate options to limit wc output.  Specifying wc  without  options
is the equivalent of specifying wc -lwc.  If any options are specified, only the requested information is output.

The  order  in which counts appear in the output line is lines, words, bytes.  If an option is omitted, then the corresponding field in the
output is omitted.  If the -m option is used, then character counts replace byte counts.

When you specify one or more files, wc displays the names of the files along with the counts.  If standard input is used, then no file name
is displayed.

EXIT STATUS
The following exit values are returned: Successful completion.  An error occurred.

EXAMPLES
To display the number of lines, words, and bytes in the file text, enter: wc text

This results in the following output: 27 185 722 text

The  numbers 27, 185, and 722 are the number of lines, words, and bytes, respectively, in the file text.	To display only one or two
of the three counts include the appropriate options. For example, the following command displays only line and byte counts:  wc  -cl
text

27  722  text  To count lines, words, and bytes in more than one file, use wc with more than one input file or with a file name pat-
tern.  For example, the following command can be issued in a directory containing the files text, text1, and text2: wc -l text*

27   text 112  text1 5	text2 144  total

The numbers 27, 112, and 5 are the numbers of lines in the files text, text1, and text2, respectively, and 144 is the  total  number
of  lines  in  the  three files.	The file name is always appended to the output.  To obtain a pure number for things like reporting
purposes, pipe all input to the wc command using cat.  For example, the following command will report the total count of	characters
in all files in a directory.  echo There are `cat *.c | wc -c` characters in *.c files

There are 1869 characters in *.c files

ENVIRONMENT VARIABLES
The  following  environment  variables affect the execution of wc: Provides a default value for the internationalization variables that are
unset or null. If LANG is unset or null, the corresponding value from the default locale is used.  If any of the internationalization vari-
ables  contain  an  invalid setting, the utility behaves as if none of the variables had been defined.  If set to a non-empty string value,
overrides the values of all the other internationalization variables.  Determines the locale for the interpretation of sequences  of  bytes
of  text data as characters (for example, single-byte as opposed to multibyte characters in arguments and input files) and which characters
are defined as white space characters.  Determines the locale for the format and contents of diagnostic messages written to standard  error
and informative messages written to standard output.  Determines the location of message catalogues for the processing of LC_MESSAGES.
