Hi MIA651,

One way using perl. It prints the file name, a colon and the number of characters in last line:
Code:
$ perl -lne 'if ( eof ) { printf qq|%s: %d\n|, $ARGV, length; }' *
3.txt: 12
AAAB.txt: 10
AAAC.txt: 26
file.data: 4

NAME
total - sum up columns SYNOPSIS
total [ -m ][ -sE | -p | -u | -l ][ -i{f|d}[N] ][ -o{f|d} ][ -tC ][ -N [ -r ]] [ file .. ] DESCRIPTION
Total sums up columns of real numbers from one or more files and prints out the result on its standard output. By default, total computes the straigt sum of each input column, but multiplication can be specified instead with the -p option. Likewise, the -u option means find the upper limit (maximum), and -l means find the lower limit (minimum). Sums of powers can be computed by giving an exponent with the -s option. (Note that there is no space between the -s and the exponent.) This exponent can be any real number, positive or negative. The absolute value of the input is always taken before the power is computed in order to avoid complex results. Thus, -s1 will produce a sum of absolute values. The default power (zero) is interpreted as a straight sum without taking absolute values. The -m option can be used to compute the mean rather than the total. For sums, the arithmetic mean is computed. For products, the geomet- ric mean is computed. (A logarithmic sum of absolute values is used to avoid overflow, and zero values are silently ignored.) If the input data is binary, the -id or -if option may be given for 64-bit double or 32-bit float values, respectively. Either option may be followed immediately by an optional count, which defaults to 1, indicating the number of double or float binary values to read per record on the input file. (There can be no space between the option and this count.) Similarly, the -od and -of options specify binary double or float output, respectively. These options do not need a count, as this will be determined by the number of input channels. A count can be given as the number of lines to read before computing a result. Normally, total reads each file to its end before producing its result, but this behavior may be overridden by inserting blank lines in the input. For each blank input line, total produces a result as if the end-of-file had been reached. If two blank lines immediately follow each other, total closes the file and proceeds to the next one (after reporting the result). The -N option (where N is a decimal integer) tells total to produce a result and reset the calculation after every N input lines. In addition, the -r option can be specified to override reinitialization and thus give a running total every N lines (or every blank line). If the end of file is reached, the current total is printed and the calculation is reset before the next file (with or without the -r option). The -tC option can be used to specify the input and output tab character. The default tab character is TAB. If no files are given, the standard input is read. EXAMPLE
To compute the RMS value of colon-separated columns in a file: total -t: -m -s2 input To produce a running product of values from a file: total -p -1 -r input BUGS
If the input files have varying numbers of columns, mean values will certainly be off. Total will ignore missing column entries if the tab separator is a non-white character, but cannot tell where a missing column should have been if the tab character is white. AUTHOR
