Thanks chatwizrd,
Can you be more explicit, I don't really understand you. The point is not to do all the actions together but one after the other. After each action is completed, I want to display a certain percentage on line one.
For example, here is a script named icandothat:
Here is the result of this script at different times (left) compared to the result of a so called script icannotdothat (right). The script I would like to be able to write is the script on the right.
T=0
T=3 seconds
T=8 seconds
T=10 seconds
does anyone know how to combine 2 lines? this is what im playing around with.

So in my shell i execute:
{ while true; do echo string; sleep 1; done } | read line This waits one second and returns.
But

I have a code:
echo "First Line ^M Second Line" | mail -s "Lines" abc@gmail.com
Basically, I want to send an email with text in this format:
First Line
Second Line
But there is something wrong with my 'echo'. The ^M is not interpreted as carriage return. Please help. (6 Replies)
Hi all,
I think this could have a simple solution, just I canīt get it so far.
I have the script below that includes several echo commands in order
to show that every part of the script have been executed. A cron job
executes this script and when is completed the output is sent by email.

echo `echo ` doesn't echoes anything. And it's logic. But
echo `echo `echo ` ` does echoes "echo". What's the logic of it? the `echo `echo ` inside of the whole (first) echo, echoes nothing, so the first echo have to echo nothing but echoes "echo"

I came across and unexpected behavior with redirections in tcsh. I know, csh is not best for redirections, but I'd like to understand what is happening here.
I have following script (called out_to_streams.csh):

ARES_QUERY(3) Library Functions Manual ARES_QUERY(3)NAME
ares_query - Initiate a single-question DNS query
SYNOPSIS
#include <ares.h>
typedef void (*ares_callback)(void *arg, int status,
int timeouts, unsigned char *abuf, int alen)
void ares_query(ares_channel channel, const char *name,
int dnsclass, int type, ares_callback callback,
void *arg)
DESCRIPTION
The ares_query function initiates a single-question DNS query on the name service channel identified by channel. The parameter name gives
the query name as a NUL-terminated C string of period-separated labels optionally ending with a period; periods and backslashes within a
label must be escaped with a backslash. The parameters dnsclass and type give the class and type of the query using the values defined in
<arpa/nameser.h>. When the query is complete or has failed, the ares library will invoke callback. Completion or failure of the query may
happen immediately, or may happen during a later call to ares_process(3) or ares_destroy(3).
The callback argument arg is copied from the ares_query argument arg. The callback argument status indicates whether the query succeeded
and, if not, how it failed. It may have any of the following values:
ARES_SUCCESS The query completed successfully.
ARES_ENODATA The query completed but contains no answers.
ARES_EFORMERR The query completed but the server claims that the query was malformatted.
ARES_ESERVFAIL The query completed but the server claims to have experienced a failure. (This code can only occur if the
ARES_FLAG_NOCHECKRESP flag was specified at channel initialization time; otherwise, such responses are ignored at the
ares_send(3) level.)
ARES_ENOTFOUND The query completed but the queried-for domain name was not found.
ARES_ENOTIMP The query completed but the server does not implement the operation requested by the query. (This code can only occur
if the ARES_FLAG_NOCHECKRESP flag was specified at channel initialization time; otherwise, such responses are ignored at
the ares_send(3) level.)
ARES_EREFUSED The query completed but the server refused the query. (This code can only occur if the ARES_FLAG_NOCHECKRESP flag was
specified at channel initialization time; otherwise, such responses are ignored at the ares_send(3) level.)
ARES_EBADNAME The query name name could not be encoded as a domain name, either because it contained a zero-length label or because it
contained a label of more than 63 characters.
ARES_ETIMEOUT No name servers responded within the timeout period.
ARES_ECONNREFUSED No name servers could be contacted.
ARES_ENOMEM Memory was exhausted.
ARES_ECANCELLED The query was cancelled.
ARES_EDESTRUCTION The name service channel channel is being destroyed; the query will not be completed.
The callback argument timeouts reports how many times a query timed out during the execution of the given request.
If the query completed (even if there was something wrong with it, as indicated by some of the above error codes), the callback argument
abuf points to a result buffer of length alen. If the query did not complete, abuf will be NULL and alen will be 0.
