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.

Code:
l_code_number := (l_src||'0011')::num

l_code_number := (l_src||'0012')::num

l_code_number := (l_src||'0012'||'.001')::num

l_code_number := (l_src||'0013')::num

l_code_number := (l_src||'0014')::num

l_code_number := (l_src||'0014'||'.001')::num
.
..
...

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?

curl_getenv(3)							  libcurl Manual						    curl_getenv(3)

NAME
curl_getenv - return value for environment name SYNOPSIS
#include <curl/curl.h> char *curl_getenv(const char *name); DESCRIPTION
curl_getenv() is a portable wrapper for the getenv() function, meant to emulate its behaviour and provide an identical interface for all operating systems libcurl builds on (including win32). AVAILABILITY
This function will be removed from the public libcurl API in a near future. It will instead be made "available" by source code access only, and then as curlx_getenv(). RETURN VALUE
If successful, curl_getenv() returns a pointer to the value of the specified environment. The memory it refers to is malloc()ed so the application must free() this when the data is no longer needed. When curl_getenv(3) fails to find the specified name, it returns a null pointer. NOTE
Under unix operating systems, there isn't any point in returning an allocated memory, although other systems won't work properly if this isn't done. The unix implementation thus has to suffer slightly from the drawbacks of other systems. SEE ALSO
