I would do it like this: my $file = “index.html”; my $document = do { local $/ = undef; open my $fh, “<“, $file or die “could not open $file: $!”; <$fh>; }; Note the use of the three-argument version of open. It is much safer than the old two- (or one-) argument versions. Also … Read more
In Bash, you can use parameter expansion to modify a string to all lower-/upper-case: var1=TesT var2=tEst echo ${var1,,} ${var2,,} echo ${var1^^} ${var2^^}
Safest & simplest is to just loop; Dim buff() As String ReDim buff(Len(my_string) – 1) For i = 1 To Len(my_string) buff(i – 1) = Mid$(my_string, i, 1) Next If your guaranteed to use ansi characters only you can; Dim buff() As String buff = Split(StrConv(my_string, vbUnicode), Chr$(0)) ReDim Preserve buff(UBound(buff) – 1)
There is no better way I know of. Bash knows only status codes (integers) and strings written to the stdout.

You can use XML Literals to achieve a similar effect: Imports System.XML Imports System.XML.Linq Imports System.Core Dim s As String = <a>Hello World</a>.Value Remember that if you have special characters, you should use a CDATA block: Dim s As String = <![CDATA[Hello World & Space]]>.Value 2015 UPDATE: Multi-line string literals were introduced in Visual Basic … Read more
Jason Scheirer’s answer is correct but could use some more exposition. First off, to repeat a string an integer number of times, you can use overloaded multiplication: >>> ‘abc’ * 7 ‘abcabcabcabcabcabcabc’ So, to repeat a string until it’s at least as long as the length you want, you calculate the appropriate number of repeats … Read more
See ?substring. x <- ‘hello stackoverflow’ substring(x, 1, 1) ## [1] “h” substring(x, 2) ## [1] “ello stackoverflow” The idea of having a pop method that both returns a value and has a side effect of updating the data stored in x is very much a concept from object-oriented programming. So rather than defining a … Read more
