I am unix newbie looking for a unix bash script that can make it easier to do my code work. we have a code number for each code block that we want to incrementally assign. We have 10000 of these and it is very laborious to do this one by one.
so what we want is start from the top of the file , look for '0000' or text below whatver number is in it. start Update with 0001 and next wherever there is number like '0000' and also has '.001' int he same line then the number repeats. .001 does not change. Example below.
If the number is more 9999 thats ok. but till 9999 it should have pad of 4 zeros 0000. Please help. no perl please. So when ever I run the script to a file, the output should have the numbers replaced inside the file or to the output file.
I am afraid that from your description I have no idea what you are trying to do.
You show us sample input that has absolutely no occurrences of the string '0000' and you do not show us the output that you want to be produced from that input.
You say that changed numbers less than 9999 should have a pad of four zeroes, but none of your samples do that. They are padded to four digits, but none of them have four leading zeroes as requested.
Please clearly explain what you are trying to do, show us sample input that shows us the various things you are trying to do (in CODE tags), and show us the corresponding output that you hope to produce from that sample input.
If you have a bunch of input files, is each file supposed to modified to change '0000' to sequential values starting at one or are the numbers to be assigned sequentially such that the same number is never assigned in more than one output file?
Where are the files that are to be used as input files? If there are files in that directory that are not to be modified, how is your script supposed to know which files are to be processed? Where are the output files to be placed?

Hi,
Appreciate any help in advance ;-)
There are some numbers between 0 and 1, 0 not included: .2500, .3333, .5000, .6666, .7500, 1.000
How to replace the first 0 ( after the dot ) with a number, say, if the number is 3:
.2500 will be .2530
.5000 will be .5300
.7500 will be .7530

Hi,
This is my first post here.
I am using cygwin on Windows 7.
I am starting with a data file with filename "name_1.ext", like "20180831_snapgenotypes_1.csv".
The "_1" before ".ext" is a version number. Integers (0-99) are sufficient. They don't have to be like "1.0.0".
The filename may... (2 Replies)

uniq
UNIQ(1) BSD General Commands Manual UNIQ(1)NAME
uniq -- report or filter out repeated lines in a file
SYNOPSIS
uniq [-c | -d | -u] [-i] [-f num] [-s chars] [input_file [output_file]]
DESCRIPTION
The uniq utility reads the specified input_file comparing adjacent lines, and writes a copy of each unique input line to the output_file. If
input_file is a single dash ('-') or absent, the standard input is read. If output_file is absent, standard output is used for output. The
second and succeeding copies of identical adjacent input lines are not written. Repeated lines in the input will not be detected if they are
not adjacent, so it may be necessary to sort the files first.
The following options are available:
-c Precede each output line with the count of the number of times the line occurred in the input, followed by a single space.
-d Only output lines that are repeated in the input.
-f num Ignore the first num fields in each input line when doing comparisons. A field is a string of non-blank characters separated from
adjacent fields by blanks. Field numbers are one based, i.e., the first field is field one.
-s chars
Ignore the first chars characters in each input line when doing comparisons. If specified in conjunction with the -f option, the
first chars characters after the first num fields will be ignored. Character numbers are one based, i.e., the first character is
character one.
-u Only output lines that are not repeated in the input.
-i Case insensitive comparison of lines.
ENVIRONMENT
The LANG, LC_ALL, LC_COLLATE and LC_CTYPE environment variables affect the execution of uniq as described in environ(7).
EXIT STATUS
The uniq utility exits 0 on success, and >0 if an error occurs.
COMPATIBILITY
The historic +number and -number options have been deprecated but are still supported in this implementation.
SEE ALSO sort(1)STANDARDS
The uniq utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002.
HISTORY
A uniq command appeared in Version 3 AT&T UNIX.
