Dotaz: Bash: read a doplňování

[David Watzke]

Ahoj. Existuje něco jako read, co doplňuje cesty? Občas bych potřeboval do skriptů - je nuda psát to bez doplňování, navíc to zdržuje a není to efektivní Dopodá to potom takhle:

$ read i
/et     po      pa      k

Myslíš něco jako ve Vimu CTRL-X CTRL-F?

[Michal Karas]

Jo aha, teď jsem si to přečetl ještě jednou a konečně mi došlo, co vlastně chceš. Tak nic.

       read [-ers] [-u fd] [-t timeout] [-a aname] [-p prompt] [-n nchars] [-d
       delim] [name ...]
              One line is read from the  standard  input,  or  from  the  file
              descriptor  fd supplied as an argument to the -u option, and the
              first word is assigned to the first name, the second word to the
              second  name, and so on, with leftover words and their interven-
              ing separators assigned to the last name.  If  there  are  fewer
              words read from the input stream than names, the remaining names
              are assigned empty values.  The characters in IFS  are  used  to
              split  the  line into words.  The backslash character (\) may be
              used to remove any special meaning for the next  character  read
              and  for line continuation.  Options, if supplied, have the fol-
              lowing meanings:
              -a aname
                     The words are assigned to sequential indices of the array
                     variable aname, starting at 0.  aname is unset before any
                     new  values  are  assigned.   Other  name  arguments  are
                     ignored.
              -d delim
                     The  first  character  of  delim is used to terminate the
                     input line, rather than newline.
              -e     If the standard input is coming from a terminal, readline
                     (see READLINE above) is used to obtain the line.
              -n nchars
                     read  returns after reading nchars characters rather than
                     waiting for a complete line of input.
              -p prompt
                     Display prompt on standard error, without a trailing new-
                     line, before attempting to read any input.  The prompt is
                     displayed only if input is coming from a terminal.
              -r     Backslash does not act as an escape character.  The back-
                     slash  is considered to be part of the line.  In particu-
                     lar, a backslash-newline pair may not be used as  a  line
                     continuation.
              -s     Silent mode.  If input is coming from a terminal, charac-
                     ters are not echoed.
              -t timeout
                     Cause read to time out and return failure if  a  complete
                     line  of  input is not read within timeout seconds.  This
                     option has no effect if read is not  reading  input  from
                     the terminal or a pipe.
              -u fd  Read input from file descriptor fd.

              If no names are supplied, the line read is assigned to the vari-
              able REPLY.  The return code  is  zero,  unless  end-of-file  is
              encountered,  read  times  out, or an invalid file descriptor is
              supplied as the argument to -u.

Tak mám pocit, že poslední dobou je moje nejčastější odpověď RTFM, ale co mám dělat, když lidi kurva zatvrzele odmítají Read This Fuckin Manual!

[barney]

skúsiť povedať ktorý manuál ?

man bash
/^ *read \[

[hm]

help read

[David Watzke]

Oops... četl jsem to moc letmo Díky.

read -e variable

je řešení.

Další dotaz Existuje totéž i pro Perl? Hodilo by se mi doplňování cesty, ale bojím se, že to nejde...
