I'm trying to create a web application which will get input from system. What this application should do is to listen what happens when some shell scripts are executing and reporting the status trough web.

Question: is there a simple sh/bash/zsh/fish/... command to print the absolute path of whichever file I feed it? Usage case: I'm in directory /a/b and I'd like to print the full path to file c on the command-line so that I can easily paste it into another program: /a/b/c. Simple, yet a little program to do this could probably save me 5 ...

I'm writing a shell script that will create a textual (i.e. diffable) dump of an archive. I'd like to detect whether or not each file is printable in some given character set, and if it is printable, I'd like to convert to that character set from whatever one it's in, if this is possible, and make its contents part of the dump. I've co...
I'm writing a pseudo shell program which creates a child from a parent process. The parent process waits for the child to finish before continuing. My forking code looks something like this: if(fork()==0) { execvp(cmd, args); } else { int status = 0; wait(&status); printf("Child exited with status of %d\n", status); ...
Hi, I've been trying to find a workaround to defining lists of sequential numbers extensively in tcsh, ie. instead of doing: i = ( 1 2 3 4 5 6 8 9 10 ) I would like to do something like this (knowing it doesn't work) i = ( 1..10 ) This would be specially usefull in foreach loops (I know I can use while, just trying to look for an a...

I've tried the following, but the resulting file is still an ELF and not purely the section content. $ objcopy --only-section=<name> <infile> <outfile> I just want the contents of the section. Is there any utility that can do this? Any ideas? ...
I'm looking for a way of processing a shell script to determine: which commands, scripts or functions are called in the script. which files are accessed by the script (r or w) . It doesn't need to recurse down through the dependencies, just list what it runs directly. I could probably write something that does this myself but it must...

However, when I pass hello into execvp(), it doesn't return any error by default and just continues running the rest of my program like nothing happen...
