You should avoid changing the "test" file when cat could still be reading it, this will become evident if your input file is large and cat hasn't buffered the whole thing before the script starts changing it.
Also, if you have a large file to process this should run a bit quicker (not calling external cut command 3 times per line):

Hi,
In ksh we use 'while read line' statement to read a file line by line. In my input file I have 5 spaces appended at the end of each line. When I use while read line statement it chops off the spaces at the end of each line

Hi Experts/Gurus,
Is there a way to remove lines in a file that are older than x days (i.e. 30 days) based on the date stamp in the first column?
Example.

shelltest
SHELLTEST(1) version 1.2.1 SHELLTEST(1)NAME
shelltestrunner - test command-line programs or arbitrary shell commands
SYNOPSIS
shelltest [options] {testfiles|testdirs}
DESCRIPTION
shelltestrunner tests command-line programs (or arbitrary shell commands). It reads simple declarative tests specifying a command, some
input, and the expected output, and can run them run in parallel, selectively, with a timeout, in color, and/or with differences high-
lighted.
OPTIONS -a, --all
Show all failure output, even if large
-c, --color
Show colored output if your terminal supports it
-d, --diff
Show failures in diff format
-p, --precise
Show failure output precisely (good for whitespace)
-x STR, --exclude=STR
Exclude test files whose path contains STR
--execdir
Run tests from within the test file's directory. Test commands normally run within your current directory; --execdir makes them run
within the directory where they are defined, instead.
--extension=EXT
Filename suffix of test files (default: .test)
-w, --with=EXECUTABLE
Replace the first word of (unindented) test commands. This option replaces the first word of all test commands with something else,
which can be useful for testing alternate versions of a program. Commands which have been indented by one or more spaces will not
be affected by this option.
--debug
Show debug info, for troubleshooting
--debug-parse
Show test file parsing info and stop
--help-format
Display test format help
-?, --help
Display help message
-V, --version
Print version information
-- TFOPTIONS
Set extra test-framework options like -j/--threads, -t/--select-tests, -o/--timeout, --hide-successes. Use -- --help for a list.
Avoid spaces.
DEFINING TESTS
Test files, typically named tests/*.test, contain one or more tests consisting of:
o a one-line command
o optional standard input (<<<), standard output (>>>) and/or standard error output (>>>2) specifications
o an exit status (>>>=) specification
Test format:
# optional comment
the command to test
<<<
zero or more lines of standard input
>>>
zero or more lines of expected standard output
(or /REGEXP/ added to the previous line)
>>>2
zero or more lines of expected standard error output
(or /REGEXP/ added to the previous line)
>>>= EXITCODE (or /REGEXP/)
o A /REGEXP/ pattern may be used instead of explicit data. In this case a match anywhere in the output allows the test to pass. The regu-
lar expression syntax is regex-tdfa (http://hackage.haskell.org/package/regex-tdfa)'s.
o EXITCODE is a numeric exit status (http://en.wikipedia.org/wiki/Exit_status), eg 0 for a successful exit.
o You can put ! before a /REGEXP/ or EXITCODE to negate the match.
o Comment lines beginning with # may be used between tests.
EXAMPLES
Here's example.test, a file containing two simple tests:
# 1. let's test that echo runs. Numbering your tests can be helpful.
echo
>>>= 0
# 2. and now the cat command. On windows, this one should fail.
cat
<<<
foo
>>>
foo
>>>= 0
Run it with shelltest:
$ shelltest example.test
:t.test:1: [OK]
:t.test:2: [OK]
