Top Forums Shell Programming and Scripting Copy of array by index value fails Post 303012762 by Don Cragun on Thursday 8th of February 2018 01:34:35 PM

The command at the end of your script:
Code:
echo ${modified_file[@]} >> $output_file

will produce a single line of output in your output file with all sequences of 1 or more adjacent <space>s, <tab>s, and <newline>s replaced by single <space>s.

But, if you input file is not a list of numbers, I missed anything in what you have shown us that would convert text to numbers. However, there is obviously a lot of code that you haven't shown us and we can't guess at what transformations might be taking place there.

If you would give us more details (like a couple of sample input files and the output files you are trying to produce from them), this does look like something that would be easy to do in ed, sed, or awk.

What operating system are you using?

NAME
asa - convert FORTRAN carriage-control output to printable form SYNOPSIS
asa [-f] [file...] DESCRIPTION
The asa utility will write its input files to standard output, mapping carriage-control characters from the text files to line-printer con- trol sequences. The first character of every line will be removed from the input, and the following actions will be performed. If the character removed is: SPACE The rest of the line will be output without change. 0 It is replaced by a newline control sequence followed by the rest of the input line. 1 It is replaced by a newpage control sequence followed by the rest of the input line. + It is replaced by a control sequence that causes printing to return to the first column of the previous line, where the rest of the input line is printed. For any other character in the first column of an input line, asa skips the character and prints the rest of the line unchanged. If asa is called without providing a filename, the standard input is used. OPTIONS
The following option is supported: -f Start each file on a new page. OPERANDS
The following operand is supported: file A pathname of a text file used for input. If no file operands are specified, or `-' is specified, then the standard input will be used. EXAMPLES
The command a.out | asa | lp converts output from a.out to conform with conventional printers and directs it through a pipe to the printer. The command asa output shows the contents of file output on a terminal as it would appear on a printer. The following program is used in the next two examples: write(*,'(" Blank")') write(*,'("0Zero ")') write(*,'("+ Plus ")') write(*,'("1One ")') end Both of the following examples produce two pages of output: Page 1: Blank ZeroPlus Page 2: One Example 1: Using actual files a.out > MyOutputFile asa < MyOutputFile | lp Example 2: Using only pipes a.out | asa | lp ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of asa: LANG, LC_ALL, LC_CTYPE, LC_MES- SAGES, and NLSPATH. EXIT STATUS
The following exit values are returned: 0 All input files were output successfully. >0 An error occurred. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ SEE ALSO
