I had a file with 150k records in it and I ran a tr on it to remove all new lines/CR which created one large record(whoops). Is there a way to add a \n after every 39th character without using 'dd' to turn it back into the original format?
dd is way to slow.
shell is ksh. (1 Reply)

Hi,
how can I join given arguments (not starting from the first one) to form one string, each argument separated by a space. For example, out of 5 given arguments, I'll like to start joining from the 3rd to the last. In python there exists something like ' '.join(sys.argv) and it starts joining... (5 Replies)

Hi. I have a piece of code that reads and parses command line options. I'd like to alter it slightly to read from a string (that's set elsewhere in the script) rather than directly from the command line (arg). Can somebody show me how to do this? Many thanks.
My code is as follows:

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
