Need complex script, anyone up for a challenge?
Default shell is /usr/bin/zsh
Script will be running #!/bin/bash
Need to pull information from database while using other scripts already made (not by me).
Ok, so i need a script pulling certain information about a customer's router interfaces.
I am using a ROUTER-DNS-NAME as variable $1
I already figured out how to obtain an output similar to the following from the SCRIPT1 that is already made:
.34
.35
After i receive those numbers, i have to run a separate script using those numbers in the end of the command, here is an example output result needed:
SCRIPT2 $1 ANYTHING.34
Having a little trouble figuring out how to connect those together within one script file.
In order for me to get first numbers i had to do a pretty long set of commands:
SCRIPT2 $1 ANYTHING | grep "`SCRIPT1 $1 | grep -i $1 | grep SOMETHING1 | grep -v NULL | cut -d"(" -f2 | cut -d"." -f1`" | cut -d"r" -f2 | cut -d" " -f1
I have SCRIPT1 interface names within SCRIPT2 to get their numbers (.34, .35 - i need that period!), then use SCRIPT2 back with those numbers.
If i use: SCRIPT2 $1 ANYTHING - this will pull all the interface info.
here is the similar output of SCRIPT1:
NODE IP(DOMAIN) STATE
----------------------------------------------- ------------------ ------
ROUTER-DNS-NAME (INTERFACE0/0) NULL(1) SOMETHING4
ROUTER-DNS-NAME (INTERFACE0/0/0:1) NULL(1) SOMETHING1
ROUTER-DNS-NAME (INTERFACE0/0/0:1.100) IPADDESS(1) SOMETHING1
Much of my script will have to contain the text formatting as per customer table punctuation. None of the names, have any specific lenght, so had to use fields.
Please advise what else i need to explain in order to get some help here.
Thank you.

cut(1) General Commands Manual cut(1)
NAME
cut - cut out (extract) selected fields of each line of a file
SYNOPSIS
list [file]...
list [file]...
list char] [file]...
DESCRIPTION
cuts out (extracts) columns from a table or fields from each line in a file; in data base parlance, it implements the projection of a rela-
tion. Fields as specified by list can be fixed length (defined in terms of character or byte position in a line when using the or option),
or the length can vary from line to line and be marked with a field delimiter character such as the tab character (when using the option).
can be used as a filter; if no files are given, the standard input is used.
When processing single-byte character sets, the and options are equivalent and produce identical results. When processing multi-byte char-
acter sets, when the and options are used together, their combined behavior is very similar, but not identical to the option.
Options
Options are interpreted as follows:
list A comma-separated list of integer byte option), character option), or field option) numbers, in increasing order,
with optional to indicate ranges. For example:
Positions 1, 4, and 7.
Positions 1 through 3 and 8.
Positions 1 through 5 and 10.
Position 3 through last position.
Cut based on a list of bytes.
Each selected byte is output unless the option is also specified.
Cut based on character positions specified by
list extracts the first 72 characters of each line).
Where list is a list of fields assumed to be separated in the file by a delimiter character (see for example, copies the
first and seventh field only. Lines with no field delimiters will be passed through intact (useful for table sub-
headings), unless is specified.
The character following
is the field delimiter option only). Default is tab. Space or other characters with special meaning to the shell
must be quoted. Adjacent field delimiters delimit null fields. char may be an international code set character.
Do not split characters.
If the high end of a range within a list is not the last byte of a character, that character is not included in the
output. However, if the low end of a range within a list is not the first byte of a character, the entire character
is included in the output."
Suppresses lines with no delimiter characters when using
option. Unless is specified, lines with no delimiters appear in the output without alteration.
Hints
Use to extract text from a file based on text pattern recognition (using regular expressions). Use to merge files line-by-line in columnar
format. To rearrange columns in a table in a different sequence, use and See grep(1) and paste(1) for more information.
EXTERNAL INFLUENCES
Environment Variables
determines the interpretation of text as single and/or multi-byte characters.
If is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty vari-
able. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization
variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5).
International Code Set Support
supports both single- and multi-byte character code sets. International code set characters may be specified in the char given to the
option. recognizes the international code set characters according to the locale specified in the environment variable.
EXAMPLES
Password file mapping of user ID to user names:
Set environment variable to current login name:
Convert file containing lines of arbitrary length into two files where contains the first 500 bytes (unless the 500th byte is within a
multi-byte character), and contains the remainder of each line:
DIAGNOSTICS
Line length must not exceed
characters or fields, including the new-line character (see limits(5).
Missing or option or incorrectly specified list. No error occurs if a line has fewer fields than the list calls for.
list is empty.
WARNINGS
does not expand tabs. Pipe text through expand(1) if tab expansion is required.
Backspace characters are treated the same as any other character. To eliminate backspace characters before processing by use the or com-
mand (see fold(1) and col(1)).
