rlam

RLAM(1) 						      General Commands Manual							   RLAM(1)

NAME

       rlam - laminate records from multiple files

SYNOPSIS

       rlam [ -tS ][ -u ][ -iaN | -ifN | -idN | -iiN | -iwN | -ibN ] input1 input2 ..

DESCRIPTION

       Rlam  simply  joins  records (or lines) from multiple inputs, separating them with the given string (TAB by default).  Different separators
       may be given for different files by specifying additional -t options in between each file name.	Note that there is no space  between  this
       option and its argument.  If none of the input files uses an ASCII separator, then no end-of-line character will be printed, either.

       An  input is either a stream or a command.  Commands are given in quotes, and begin with an exclamantion point ('!').  If the inputs do not
       have the same number of lines, then shorter files will stop contributing to the output as they run out.

       The -ia option may be used to specify ASCII input (the default), or the -if option may be used to indicated binary IEEE	32-bit	floats	on
       input.	Similarly,  the  -id and -ii options may be used to indicate binary 64-bit doubles or integer words, respectively.  The -iw option
       specifies 2-byte short words, and the -ib option specifies bytes.  If a number is immediately follows any of these options, then  it  indi-
       cates that multiple such values are expected for each record.  For example, -if3 indicates three floats per input record for the next named
       input.  In the case of the -ia option, no number indicates one line per input record, and numbers greater  than	zero  indicate	that  many
       characters  exactly  per  record.   For binary input formts, no number implies one value per record.  For anything other than EOL-separated
       input, the default tab separator is reset to the empty string.

       A hyphen ('-') by itself can be used to indicate the standard input, and may appear multiple times.  The -u option forces output after each
       record (i.e., one run through inputs).

EXAMPLE

       To join files output1 and output2, separated by a comma:

	 rlam -t, output1 output2

       To join a file with line numbers (starting at 0) and its reverse:

	 cnt `wc -l < lam.c` | rlam - -t: lam.c -t '!tail -r lam.c'

       To join four data files, each having three doubles per record:

	 rlam -id3 file1.dbl file2.dbl file3.dbl file4.dbl > combined.dbl
