This is another example of why you should always tell us what operating system and shell you're using when you post a question in this forum.

From what I have seen in other threads in this forum recently, you might get the output you wanted with your code if you were running it on a Linux system. You certainly will not get what you want (and will get what you are seeing) if you run it on a UNIX or BSD system.

Either of the following should work reliably on any of these systems:

Code:

printf "%s\n" "Number of transactions in $i : `cat $i | tail +2 | wc -l`" >> ${LOG_FILE}

(which may produce varying numbers of spaces between the colon and the following number) or:

Code:

printf 'Number of transactions in %s : %d\n' "$i" `tail +2 "$i" | wc -l`  >> ${LOG_FILE}

(which will only put one space between the colon and the number of lines in the truncated file).

It would also be more efficient if you moved the redirection from the printf to the end of the outer loop.

uuencode(5) File Formats Manual uuencode(5)

Name
uuencode - format of an encoded uuencode file

Description
Files output by consist of a header line, followed by a number of body lines, and a trailer line. The command ignores any lines preceding
the header or following the trailer. Lines preceding a header must not, of course, look like a header.

The header line is distinguished by having the first six characters by the word ``begin'', followed by a space. The next item on the line
is a mode (in octal) and a string which names the remote file. A space separates the three items in the header line.

The body consists of a number of lines, each at most 62 characters long including the trailing new line. These consist of a character
count, followed by encoded characters, followed by a new line. The character count is a single printing character and represents an inte-
ger, the number of bytes the rest of the line represents. Such integers are always in the range from 0 to 63 and can be determined by sub-
tracting the character space (octal 40) from the character.

Groups of 3 bytes are stored in 4 characters, with 6 bits per character. All are offset by a space to make the characters print. The last
line may be shorter than the normal 45 bytes. If the size is not a multiple of 3, this fact can be determined by the value of the count on
the last line. Extra dummy characters are included to make the character count a multiple of 4. The body is terminated by a line with a
count of zero. This line consists of one ASCII space.

The trailer line consists of "end" on a line by itself.
