Good day, great gurus,
I'm new to Perl, and programming in general. I'm trying to retrieve a column of data from my text file which spans a non-specific number of lines. So I did a regexp that will pick out the columns. However,my pattern would vary. I tried using a foreach loop unsuccessfully.... (2 Replies)
I need to replace a piece of text in many files, recursively, in a way that doesn't duplicate the files. How would I do that?
The closest I've come is
grep -rl "text" * | sed -e 's/home1/home2/g'
but that just replaces the filename. (2 Replies)

I am able to grep multiple patterns which stored in a files. However, how could we replace the whole line with either the pattern or new string?

switch
switch(n) Tcl Built-In Commands switch(n)
__________________________________________________________________________________________________________________________________________________NAME
switch - Evaluate one of several scripts, depending on a given value
SYNOPSIS
switch ?options? string pattern body ?pattern body ...?
switch ?options? string {pattern body ?pattern body ...?}
_________________________________________________________________DESCRIPTION
The switch command matches its string argument against each of the pattern arguments in order. As soon as it finds a pattern that matches
string it evaluates the following body argument by passing it recursively to the Tcl interpreter and returns the result of that evaluation.
If the last pattern argument is default then it matches anything. If no pattern argument matches string and no default is given, then the
switch command returns an empty string.
If the initial arguments to switch start with - then they are treated as options. The following options are currently supported:
-exact Use exact matching when comparing string to a pattern. This is the default.
-glob When matching string to the patterns, use glob-style matching (i.e. the same as implemented by the string match command).
-regexp When matching string to the patterns, use regular expression matching (as described in the re_syntax reference page).
-- Marks the end of options. The argument following this one will be treated as string even if it starts with a -.
Two syntaxes are provided for the pattern and body arguments. The first uses a separate argument for each of the patterns and commands;
this form is convenient if substitutions are desired on some of the patterns or commands. The second form places all of the patterns and
commands together into a single argument; the argument must have proper list structure, with the elements of the list being the patterns
and commands. The second form makes it easy to construct multi-line switch commands, since the braces around the whole list make it unnec-
essary to include a backslash at the end of each line. Since the pattern arguments are in braces in the second form, no command or vari-
able substitutions are performed on them; this makes the behavior of the second form different than the first form in some cases.
If a body is specified as ``-'' it means that the body for the next pattern should also be used as the body for this pattern (if the next
pattern also has a body of ``-'' then the body after that is used, and so on). This feature makes it possible to share a single body among
several patterns.
Beware of how you place comments in switch commands. Comments should only be placed inside the execution body of one of the patterns, and
not intermingled with the patterns.
Below are some examples of switch commands:
switch abc a - b {format 1} abc {format 2} default {format 3}
will return 2,
switch -regexp aaab {
^a.*b$ -
b {format 1}
a* {format 2}
default {format 3}
}
will return 1, and
switch xyz {
a
-
b
{
# Correct Comment Placement
format 1
}
a*
{format 2}
default
{format 3}
}
will return 3.
