Hallo Everyone.
I have to admit I'm shell scripting illiterate . I need to find certain strings in several text files and replace each of the string by unique & corresponding text.
I prepared a csv file with 3 columns: <filename>;<old_pattern>;<new_pattern>

I would like to use printf (or something else?) to create a line of text that has varying column widths. This will be used to create a fixed width file (with varying column widths). For example, consider variables $1 $2 $3 are equal to a, b, c respectively and they should be printed in column... (10 Replies)

string::shellquote
ShellQuote(3) User Contributed Perl Documentation ShellQuote(3)NAME
String::ShellQuote - quote strings for passing through the shell
SYNOPSIS
$string = shell_quote @list;
$string = shell_quote_best_effort @list;
$string = shell_comment_quote $string;
DESCRIPTION
This module contains some functions which are useful for quoting strings which are going to pass through the shell or a shell-like object.
shell_quote [string]...
shell_quote quotes strings so they can be passed through the shell. Each string is quoted so that the shell will pass it along as a
single argument and without further interpretation. If no strings are given an empty string is returned.
If any string can't be safely quoted shell_quote will croak.
shell_quote_best_effort [string]...
This is like shell_quote, excpet if the string can't be safely quoted it does the best it can and returns the result, instead of dying.
shell_comment_quote [string]
shell_comment_quote quotes the string so that it can safely be included in a shell-style comment (the current algorithm is that a sharp
character is placed after any newlines in the string).
This routine might be changed to accept multiple string arguments in the future. I haven't done this yet because I'm not sure if the
strings should be joined with blanks ($") or nothing ($,). Cast your vote today! Be sure to justify your answer.
EXAMPLES
$cmd = 'fuser 2>/dev/null ' . shell_quote @files;
@pids = split ' ', `$cmd`;
print CFG "# Configured by: ",
shell_comment_quote($ENV{LOGNAME}), "
";
BUGS
Only Bourne shell quoting is supported. I'd like to add other shells (particularly cmd.exe), but I'm not familiar with them. It would be
a big help if somebody supplied the details.
