Shell Programming and Scripting

It works as you see. If you have basic understanding of awk, It works in
/pattern/ {action} mode.

Code:

awk -v newLocation=Bangalore '                     #define awk variable newLocation
	/^location/ {$2=newLocation";"}            #look for location line and replace $2 with newLocation plus ";" at the end
	/^travelID/ {tID=$2;gsub(";$"," ",tID)}    #look for travelID line and store the $2 with tID variable, gsub is to remove the ";" from the end
	/^\}$/ {f=1}                               #look for line contains "}" and set a flag f to true
	f==1 && /^[0-9]+$/ {$0=tID $0;f=0}         #look for line immd followed by the upper criteria AND contains only numbers, prefix the file with variable tID
	/^\)$/ {$0=$0";"}                          #suffix ";" after ")"
	{print}' file > new_file #print all the lines.

you are so kind

Hi again,
Let me guess you have great touch with C++ as well.
Sorry to bother you. I need little help in shell operations from C++ program.
Here I furnish the details of problem:
1. Lets say my current working path is myWorkingPath.
2. In my working path I have list of name directories and each name directory has two more sub directories say A/B.
(now path to B will be pathB = myWorkingPath/name/A/B)
3. I have a executable (say run) in myWorkingPath directory, that i wanted to execute from B directory.
4. From C++ program I can do shell operations like mkdir, rm etc using system("mkdir NewDir"), system("rm file") etc., (these shell operations will done form myWorkingPath)
but unable to do some shell operations from pathB. How can I communicate pathB for system() operations?

lets say I have saved this path in

Code:

pathB="/home/linuxUser/myWorkingPath/name/A/B"

. here name is a variable.

Code:

for(i=0;i<nameList.size(); i++){
    pathB="/home/linuxUser/myWorkingPath"/nameList.name(i)/"A/B";
    system("cd pathB"); // to goto that B directory
    system("../../../run"); // to run the executable
}

I know this program is wrong but, may give you clear idea what i wanted to do.

can you help me?

Regards,
