Standard input is used for a file name of '-' or if no input files are given. Synopsis: paste [OPTION]... [FILE]... For example, with: $ cat num2 1 2 $ cat let3 a b c Take lines sequentially from each file: $ paste num2 let3 1 a 2 b c Duplicate lines from a file: $ paste num2 let3 num2 1 a 1 2 b 2 c Intermix lines from stdin: $ paste - let3 - < num2 1 a 2 b c Join consecutive lines with a space: $ seq 4 | paste -d ' ' - - 1 2 3 4 The program accepts the following options. Also see *note Common options::. '-s' '--serial' Paste the lines of one file at a time rather than one line from each file. Using the above example data: $ paste -s num2 let3 1 2 a b c '-d DELIM-LIST' '--delimiters=DELIM-LIST' Consecutively use the characters in DELIM-LIST instead of TAB to separate merged lines. When DELIM-LIST is exhausted, start again at its beginning. Using the above example data: $ paste -d '%_' num2 let3 num2 1%a_1 2%b_2 %c_ '-z' '--zero-terminated' Delimit items with a zero byte rather than a newline (ASCII LF). I.e., treat input as items separated by ASCII NUL and terminate output items with ASCII NUL. This option can be useful in conjunction with 'perl -0' or 'find -print0' and 'xargs -0' which do the same in order to reliably handle arbitrary file names (even those containing blanks or other special characters). An exit status of zero indicates success, and a nonzero value indicates failure.
