  $(lst_syntax)replace [internal] $emph s1 $emphend by $emph s2 $emphend in $emph

  string$emphend<br>

  </tt>or <tt>!replace $emph obj$emphend $emph ident$emphend by

  $emph s$emphend in $emph string$emphend</tt> <br>

  $lst_mean String manipulation. <p>

  Under the first syntax, variable substitution is first done on

  $emph string$emphend. Then all occurences of substring $emph s1$emphend

  are replaced by $emph s2$emphend. <br>

  When the keyword $emph internal $emphend is absent,

  the Linux utility $emph sed$emphend is called to make the replacements,

  therefore regular expressions are accepted in $emph s1$emphend and

  $emph s2$emphend. Please refer to the man page of $emph sed$emphend for

  details. <p>

  Under the second syntax, $emph obj$emphend can be $emph char$emphend,

  $emph word$emphend,

  $emph item$emphend or $emph line$emphend. Then the word, item or line

  identified by $emph ident$emphend in $emph string$emphend is replaced

  by $emph s$emphend, after variable substitutions. <br>

  $emph ident$emphend can be a string, in this case all objects

  (words, items or lines) matching

  $emph ident$emphend will be replaced. It can also be a number (positive or

  negative integer $emph n$emphend), preceded

  by the word $emph number$emphend. In this case the object

  number $emph n$emphend will be replaced. (In the case where n<0,

  it is the last -n'th object which is replaced.)
