I am very thankful to you Don Cragun for helping me in writing scripts and explaining them as well.
I am very new in this field of shell scripting but I cannot rely on other programming language because I am not expert in any language. I have started reading shell scripting books, but its difficult for me to figure out what to write in a script. I don't know sometimes what are the functions or commands available in shell scripting I can use. But, when you write script then I come to know about lot of things and I try to read it.
I know I should write my own script and post here for help, but sometimes even I am unable to guess how I have to start. I have found this forum as my best guide on the internet.
I am adding more information and real values for the last post.
atom.txt has less than 1000 entries, so Ids don't have more than 3 digits.
There are 30 values in Group 10 with comma separator, Group 72 has 26 values and so on, Id_of_Branches means number of values in each group.
There are not 33 fields on every line (one for Group ID, one for Centre ID, one for Branches ID, and one for each of 30 branches). There are not 3 + value_of_3rd_field fields?
I have two files and I combined them into one g.txt (using comma separator for Id_of branches), two files are:
Code:
First file:
Group: 0 Number of Branches: 1
0 001
Centre: 001 Branches: 1
Group: 1 Number of Branches: 1
0 002
Centre: 002 Branches: 1
Group: 2 Number of Branches: 1
0 003
Centre: 003 Branches: 1
Group: 3 Number of Branches: 6
0 009
1 004
2 008
3 007
4 005
5 006
Centre: 006 Branches: 6
Group: 4 Number of Branches: 2
0 010
1 011
Centre: 010 Branches: 2
Group: 5 Number of Branches: 2
0 012
1 013
Centre: 012 Branches: 2
Upto more than 600 groups
Second file:
Group No:
10 Centre: 052 Branches: 31
73 Centre: 184 Branches: 25
397 Centre: 607 Branches: 23
398 Centre: 640 Branches: 22
86 Centre: 245 Branches: 19
71 Centre: 167 Branches: 12
78 Centre: 220 Branches: 11
18 Centre: 084 Branches: 10
09 Centre: 022 Branches: 10
400 Centre: 650 Branches: 9
I wish to have 10 files for 10 groups (as per second file) each with pattern corresponding to the Id _of_Branches (from first file) in each group.
Centre.txt (only one file) is supposed to contain patterns corresponding to Centre Id from each group.
Hello,

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
