cat in linux, file holding special charcters
Hi
I'd like to cat, in linux, a file that holds special charcters, like "-->" and ">" and "]"
For example I have a file named test123.txt
it looks like this:
2008-09-11 00:27:01,496 -
< 0 > --> Start calculation of pattern [PROCESS_complex3], Pattern was split to [1] pattern graphs
< 0 > System Tqls Optimizer going to ask System Tqls results for all graph's elements except [-13]
< 16 > System Tqls Optimizer got System tqls results for [-11]
< 16 > Entered OverallPatternGraphCalculator witks [2] ; -15(-11 --> -13) - container_f ; -19(-11 --> -17) - container_f] calculation size [0 consistent=true]
< 16 > Entered ComponentGraphCalculator with component [Num of nodes [3] ; -17 - process ; -13 - disk ; -11 - host Num of links [2] ; -15(-11 --> -13) - container_f ; -19(-11 --> -17) - container_f, elements size 0] calculation size [0 consistent=true]
< 16 > Entered CompositeCalcul [2] ; -15(-11 --> -13) - container_f ; -19(-11 --> -17) - container_f, elements size 0] calculation size [0 consistent=true]
< 7500 > Calculation ended, result size [1769 consistent=false]
< 7500 > Calculation ended, result size [1769 consistent=false]
< 7500 > Entered ConsistencyChe- process ; -13 - disk ; -11 - host Num of links [2] ; -15(-11 --> -13) - container_f ; -19(-11 --> -17) - container_f] calculation size [1769 consistent=false]
< 7500 > Consistency at pattern level was found to be required due to previous calculation inconsistency
< 7516 > Calculation ended, result size [1769 consistent=false]
< 7516 > Calculation ended, result size [1769 consistent=false]
< 7516 > Result size [1769]
I want to cat it, the result should be:
< 0 > --> Start calculation of pattern [PROCESS_complex3], Pattern was split to [1] pattern graphs
< 7516 > Result size [1769]
I tried varations of the following command:
cat test123.txt | grep "> --> Start calculation of pattern [" | grep "> Result size ["
I tried it with one '
and with \ before the special chars etc...
Any Ideas ?
Thanks

fc-pattern - parse and show pattern SYNOPSIS
fc-pattern [ -cdVh ] [ --config ] [ --default ] [ [ -f format ] [ --format format ] ] [ --version ] [ --help ] [ pattern [ element... ] ] DESCRIPTION
fc-pattern parses pattern (empty pattern by default) and shows the parsed result. If --config is given, config substitution is performed on the pattern before being displayed. If --default is given, default substitution is performed on the pattern before being displayed. If any elements are specified, only those are printed. OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. -c Perform config substitution on pattern. -d Perform default substitution on pattern. -f Format output according to the format specifier format. -V Show version of the program and exit. -h Show summary of options. pattern Parses and displays pattern (uses empty pattern by default). element If set, the element property is displayed for parsed pattern.
