Replace all string matches in file with unique random number
Hello
Take this file...
Code:
Test01
Ref test
Version 01
Test02
Ref test
Version 02
Test66
Ref test
Version 66
Test99
Ref test
Version 99
I want to substitute every occurrence of Test[0-9]{2} with a unique random number, so for example, if I was using sed, substitution would be something like the below but obviously the below does reevaluate the random number for each occurrence of Test[0-9]{2}
Code:
num=$((1+RANDOM 20 % 60))
sed -ri "s/Test[0-9]{2}/Test${num}/" test_file
So on the execution of substitution, the file would read something like
Code:
Test59
Ref test
Version 01
Test57
Ref test
Version 02
Test48
Ref test
Version 66
Test51
Ref test
Version 99

Hello,
in my shell script i have some multi-line text in a variable $TEMP - f.e.

And i need to replace TARGET with text from another variable ($REPLACE), which is containing some text with nasty characters (\n, ", :, etc.) And stuff the altered text... (2 Replies)
Hi Can someone help me with this one?

I need a sed line that will take STDM111 and change it to STDM161
the STDM will always be constant but the 3 numbers after will be random, I just need it to always replace the middle number with 6 regardless of what the numbers are. (8 Replies)

Hi all,
I need to run a number of scripts which have a certain phrase on them so I have identified these by;
grep -l 100 *script | sort -u
Normally I could just run something along the lines of;
for i in `grep -l 100 *script | sort -u`; do ./${i}; done
However before I run each of... (0 Replies)
Hi experts,
My csv file looks like this

ic_c_protocol(3erl) C Library Functions ic_c_protocol(3erl)NAME
ic_c_protocol - IC C Protocol Functions
DESCRIPTION
This manual page lists some of the functions of the IC C runtime library that are used internally for the IC protocol.
The listed functions are used internally by generated C client and server code. They are documented here for the advanced user that want to
replace the default protocol (Erlang distribution + gen_server) by his own protocol, For each set of client or sever functions below with
prefix oe , the user has to implement his own set of functions, the names of which are obtained by replacing the oe prefix by Prefix . The
Prefix has to be set with the option {user_protocol, Prefix} at compile time.
The following terminology is used (reflected in names of functions): a notification is a message send from client to server, without any
reply back (i.e. a oneway operation); a request is a message sent from client to server, and where a reply message is sent back from the
server to the client.
In order to understand how the functions work and what they do the user must study their implementation in the IC C library (source file is
ic.c ), and also consider how they are used in the C code of ordinary generated client stubs or server skeletons.
CLIENT PROTOCOL FUNCTIONS
The following functions are used internally by generated C client code.
EXPORTS
int oe_prepare_notification_encoding(CORBA_Environment *env)
The result of this function is the beginning of a binary of in external format of the tuple {'$gen_cast', X} where X is not yet
filled in.
In generated client code this function is the first to be called in the encoding function for each oneway operation.
int oe_send_notification(CORBA_Environment *env)
int oe_send_notification_tmo(CORBA_Environment *env, unsigned int send_ms)
Sends a client notification to a server according to the Erlang distribution + gen_server protocol.
The send_ms parameter specified a timeout in milliseconds.
int oe_prepare_request_encoding(CORBA_Environment *env)
The result of this function is the beginning of a binary in the external format of the tuple {'$gen_call', {Pid, Ref}, X} where X is
not yet filled in.
In generated client code this function is the first to be called in the encoding function for each twoway operation.
int oe_send_request_and_receive_reply(CORBA_Environment *env)
int oe_send_request_and_receive_reply_tmo(CORBA_Environment *env, unsigned int send_ms, unsigned int recv_ms)
Sends a client request and receives the reply according to the Erlang distribution + gen_server protocol. This function calls the
oe_prepare_reply_decoding function in order to obtain the gen_server reply.
send_ms and recv_ms specify timeouts for send and receive, respectively, in milliseconds.
int oe_prepare_reply_decoding(CORBA_Environment *env)
Decodes the binary version of the tuple {Ref, X} , where X is to be decoded later by the specific client decoding function.
SERVER PROTOCOL FUNCTIONS
The following functions are used internally by generated C server code.
EXPORTS
int oe_prepare_request_decoding(CORBA_Environment *env)
Decodes the binary version of the tuple {'$gen_cast', Op} ( Op an atom), or the tuple {'$gen_cast', {Op, X}} , where Op is the oper-
ation name, and where X is to be decoded later by the specific operation decoding function; or
decodes the binary version of the tuple {'$gen_call', {Pid, Ref}, Op} ( Op an atom), or the tuple {'$gen_call', {Pid, Ref}, {Op, X}}
, where Op> is the operation name, and X is to be decode later by the specific operation decoding function.
int oe_prepare_reply_encoding(CORBA_Environment *env)
Encodes the beginning of the binary version of the tuple {{Ref,X} , where X is to be filled in by the specific server encoding func-
tion.
