I'm creating a bsh shell to unzip a file from one directory into another. The directory that holds the zip files has zip files constantly being added to it, so I am testing it before it does the unzip and more.
Right now my code looks like this:
unzip -tq $ZIP_PATH/$ZIP_NAME >/dev/null

I'm having trouble with part of this bash script in Linux where I respawn a new instance of script and kill the old one to prevent forking (Yes, I know 'exec' will not fork but this needs to be interactive) When the old instance is kill it pops up "Terminated!" in the middle of the new instance...

DIRECTORY(3) Library Functions Manual DIRECTORY(3)NAME
opendir, readdir, telldir, seekdir, rewinddir, closedir - directory operations
SYNOPSIS
#include <sys/types.h>
#include <sys/dir.h>
DIR *opendir(filename)
char *filename;
struct direct *readdir(dirp)
DIR *dirp;
long telldir(dirp)
DIR *dirp;
seekdir(dirp, loc)
DIR *dirp;
long loc;
rewinddir(dirp)
DIR *dirp;
closedir(dirp)
DIR *dirp;
DESCRIPTION
Opendir opens the directory named by filename and associates a directory stream with it. Opendir returns a pointer to be used to identify
the directory stream in subsequent operations. The pointer NULL is returned if filename cannot be accessed, or if it cannot malloc(3)
enough memory to hold the whole thing.
Readdir returns a pointer to the next directory entry. It returns NULL upon reaching the end of the directory or detecting an invalid
seekdir operation.
Telldir returns the current location associated with the named directory stream.
Seekdir sets the position of the next readdir operation on the directory stream. The new position reverts to the one associated with the
directory stream when the telldir operation was performed. Values returned by telldir are good only for the lifetime of the DIR pointer
from which they are derived. If the directory is closed and then reopened, the telldir value may be invalidated due to undetected direc-
tory compaction. It is safe to use a previous telldir value immediately after a call to opendir and before any calls to readdir.
Rewinddir resets the position of the named directory stream to the beginning of the directory.
Closedir closes the named directory stream and frees the structure associated with the DIR pointer.
Sample code which searchs a directory for entry ``name'' is:
len = strlen(name);
dirp = opendir(".");
for (dp = readdir(dirp); dp != NULL; dp = readdir(dirp))
if (dp->d_namlen == len && !strcmp(dp->d_name, name)) {
closedir(dirp);
return FOUND;
}
closedir(dirp);
return NOT_FOUND;
