Hi,

Yes, you can provide ranges of special characters in both sed and tr or you can work with one character at a time. All the information that you require should be in the man pages on your system, you can try man tr this would be a good place to start.

NAME
paste - merge same lines of several files or subsequent lines of one file SYNOPSIS
file1 file2 ... list file1 file2 ... list] file1 file2 ... DESCRIPTION
In the first two forms, concatenates corresponding lines of the given input files file1, file2, etc. It treats each file as a column or columns in a table and pastes them together horizontally (parallel merging). In other words, it is the horizontal counterpart of cat(1) which concatenates vertically; i.e., one file after the other. In the option form above, replaces the function of an older command with the same name by combining subsequent lines of the input file (serial merging). In all cases, lines are glued together with the tab char- acter, or with characters from an optionally specified list. Output is to standard output, so can be used as the start of a pipe, or as a filter if is used instead of a file name. recognizes the following options and command-line arguments: Without this option, the new-line characters of all but the last file (or last line in case of the option) are replaced by a tab character. This option allows replac- ing the tab character by one or more alternate characters (see below). list One or more characters immediately following replace the default tab as the line concatenation character. The list is used circularly; i.e., when exhausted, it is reused. In parallel merging (that is, no option), the lines from the last file are always terminated with a new-line character, not from the list. The list can contain the special escape sequences: (new-line), (tab), (backslash), and (empty string, not a null character). Quoting may be necessary if charac- ters have special meaning to the shell. (For example, to get one backslash, use ). Merge subsequent lines rather than one from each input file. Use tab for concatenation, unless a list is specified with the option. Regardless of the list, the very last character of the file is forced to be a new-line. Can be used in place of any file name to read a line from the standard input (there is no prompting). EXTERNAL INFLUENCES
Environment Variables determines the locale for the interpretation of text as single- and/or multi-byte characters. determines the language in which messages are displayed. If or is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty variable. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5). International Code Set Support Single- and multi-byte character code sets are supported. RETURN VALUE
These commands return the following values upon completion: Completed successfully. An error occurred. EXAMPLES
List directory in one column: List directory in four columns Combine pairs of lines into lines Notes works similarly, but creates extra blanks, tabs and new-lines for a nice page layout. DIAGNOSTICS
Except for the option, no more than - 3 input files can be specified (see limits(5)). AUTHOR
