@ The tab chars are in my code, copy paste preserves them usualy.

Thanks for your feedback, sadly i seem to apply this somehow wrong...

Function:

Code:

	PlayStatus() { # FILE
	# Prints the extra status play bar
	# Time as Progress, yay 
		# Vars
		PT=$(PlayTime)		# Get nice displayed playtime
		PTS=$(PlayTimeSecs)	# Get playtime as seconds
		[ "00" = "${PT:0:2}" ] && \
			PT="${PT/00:}"	# Cut off 'empty' leading hours
		PT="${PT/.*}"		# Cut off miliseconds
		STATUS="$TMP.playstatus"
		
		# Make required changes at the command file
		$SED s,'v quiet','hide_banner',g -i "$TMP"
		#$SED s,"||","1\>$STATUS 2\>$STATUS ||",g -i "$TMP"
		$SED s,"||"," 2\>$STATUS ||",g -i "$TMP"
		
		# Start job
		$SHELL "$TMP" &
		PID=$!
		sleep 0.7
		
		# TMP command
		tui-title "DIV"
		tui-cat $TMP
		tui-title "DIV"
		
		# Print information line
		while ps $PID > /dev/null
		do	CUR=$(tail -n1 "$STATUS"|awk '{print $1}')
			echo tui-progress -bm "$PTS" -c "$CUR" "$CUR/$PT"
			sleep 0.7
		done
		return
}

sh -x : output, still doesnt update the $CUR variable Smilie

copymsg

copymsg(9F)						   Kernel Functions for Drivers 					       copymsg(9F)

NAME

       copymsg - copy a message

SYNOPSIS

       #include <sys/stream.h>

       mblk_t *copymsg(mblk_t *mp);

INTERFACE LEVEL

       Architecture independent level 1 (DDI/DKI).

PARAMETERS

       mp	Pointer to the message to be copied.

DESCRIPTION

       copymsg()  forms  a  new  message  by  allocating  new message blocks, and copying the contents of the message referred to by mp (using the
       copyb(9F) function). It returns a pointer to the new message.

RETURN VALUES

       If the copy is successful, copymsg() returns a pointer to the new message.  Otherwise, it returns a NULL pointer.

CONTEXT

       copymsg() can be called from user or interrupt context.

EXAMPLES

       Example 1: : Using copymsg

       The routine lctouc() converts all the lowercase ASCII characters in the message to uppercase. If the reference count is	greater  than  one
       (line  8),  then  the  message  is shared, and must be copied before changing the contents of the data buffer. If the call to the copymsg()
       function fails (line 9), return NULL (line 10), otherwise, free the original message (line 11). If the reference count was equal to 1,  the
       message can be modified. For each character (line 16) in each message block (line 15), if it is a lowercase letter, convert it to an upper-
       case letter (line 18). A pointer to the converted message is returned (line 21).

       11	     freemsg(mp);
       12    } else {
       13	     cmp = mp;
       14    }
       15    for (tmp = cmp; tmp; tmp = tmp->b_cont) {
       16	     for (cp = tmp->b_rptr; cp < tmp->b_wptr; cp++) {
       17		     if ((*cp <= 'z') && (*cp >= 'a'))
