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

CHSH(1) User Commands CHSH(1) NAME
chsh - change your login shell SYNOPSIS
chsh [-s shell] [-l] [-u] [-v] [username] DESCRIPTION
chsh is used to change your login shell. If a shell is not given on the command line, chsh prompts for one. chsh is used to change local entries only. Use ypchsh, lchsh or any other implementation for non-local entries. OPTIONS
-s, --shell shell Specify your login shell. -l, --list-shells Print the list of shells listed in /etc/shells and exit. -u, --help Print a usage message and exit. -v, --version Print version information and exit. VALID SHELLS
chsh will accept the full pathname of any executable file on the system. However, it will issue a warning if the shell is not listed in the /etc/shells file. On the other hand, it can also be configured such that it will only accept shells listed in this file, unless you are root. EXIT STATUS
Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid. SEE ALSO
login(1), passwd(5), shells(5) AUTHOR
Salvatore Valente <svalente@mit.edu> AVAILABILITY
The chsh command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. util-linux July 2009 CHSH(1)
