hi all,

Hi,
I am a beginner in shell scripting. I have written the following script, which is supposed to process the while loop for each line in the sid_home.txt file. But I'm getting the 'end of file' unexpected for the last line. The file sid_home.txt gets generated as expected, but the script... (6 Replies)

So:

the problem is that sed does not seem to recognise the $a, even when trying

I have written a script to read the file line by line.
It is reading and printing the lines.
But it is coming out of loop before reading last line.
So I am not able to print last line.

I need some help. I would like to read in a text file.
Take a variable such as ROW-D-01, compare it to what's in one line in the text file such as PROD/VM/ROW-D-01 and only input PROD/VM into a variable without the /ROW-D-01.
Is this possible? any help is appreciated. (2 Replies)

text::diff::table
Text::Diff::Table(3pm) User Contributed Perl Documentation Text::Diff::Table(3pm)NAME
Text::Diff::Table - Text::Diff plugin to generate "table" format output
SYNOPSIS
use Text::Diff;
diff @a, $b { STYLE => "Table" };
DESCRIPTION
This is a plugin output formatter for Text::Diff that generates "table" style diffs:

+--+----------------------------------+--+------------------------------+
This format also goes to some pains to highlight "invisible" characters on differing elements by selectively escaping whitespace. Each
element is split in to three segments (leading whitespace, body, trailing whitespace). If whitespace differs in a segement, that segment
is whitespace escaped.
Here is an example of the selective whitespace.

Here's why the lines do or do not have whitespace escaped:
lines 1, 4, 7 don't differ, no need.
lines 2, 3 differ in non-whitespace, no need.
lines 5, 6, 8, 9 all have subtle ws changes.
Whether or not line 3 should have that tab character escaped is a judgement call; so far I'm choosing not to.
UNICODE
To output the raw unicode chracters consult the documentation of Text::Diff::Config. You can set the "DIFF_OUTPUT_UNICODE" environment
variable to 1 to output it from the command line. For more information, consult this bug:
<https://rt.cpan.org/Ticket/Display.html?id=54214> .
LIMITATIONS
Table formatting requires buffering the entire diff in memory in order to calculate column widths. This format should only be used for
smaller diffs.
Assumes tab stops every 8 characters, as $DIETY intended.
Assumes all character codes >= 127 need to be escaped as hex codes, ie that the user's terminal is ASCII, and not even "high bit ASCII",
capable. This can be made an option when the need arises.
Assumes that control codes (character codes 0..31) that don't have slash-letter escapes ("
", "
", etc) in Perl are best presented as hex
escapes ("x01") instead of octal ("
