I am attempting to write a korn shell script that does the following, but I am getting errors. I'm new to korn shell scripting and am not sure what I am doing wrong. Please help with example scripts. Thanks.
1) check for day of the week
2) if day of the week is Monday then check for the existence of three files
3) if all three files are not found then loop infinitely until all three are found
4) when found then execute a .sas program
5) else if the day if the week is not Monday then check for the existence of two files
6) if the two files are not found then loop infinitely until both files are found
7) when both files are found execute a .sas program
Here's what I have thus far:
Code:
#!/usr/bin/ksh
. ~/.profile
DAYOFWEEK=$(date +"%u")
echo DAYOFWEEK: $DAYOFWEEK
if ["$DAYOFWEEK" == 1];
then do
if [-f /files/are/here/FILE1.txt
-f /files/are/here/FILE2.txt
-f /files/are/here/FILE3.txt]; then
sas /files/are/here/process.sas
sleep 10
else if ["$DAYOFWEEK" !==1];
then do
if [-f /files/are/here/FILE2.txt
-f /files/are/here/FILE3.txt]; then
sas /files/are/here/process.sas
sleep 10
done

script
SCRIPT(1) BSD General Commands Manual SCRIPT(1)NAME
script -- make typescript of terminal session
SYNOPSIS
script [-a] [-c COMMAND] [-e] [-f] [-q] [-t] [file]
DESCRIPTION
Script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
Options:
-a Append the output to file or typescript, retaining the prior contents.
-c COMMAND
Run the COMMAND rather than an interactive shell. This makes it easy for a script to capture the output of a program that behaves
differently when its stdout is not a tty.
-e Return the exit code of the child process. Uses the same format as bash termination on signal termination exit code is 128+n.
-f Flush output after each write. This is nice for telecooperation: One person does `mkfifo foo; script -f foo' and another can super-
vise real-time what is being done using `cat foo'.
-q Be quiet.
-t Output timing data to standard error. This data contains two fields, separated by a space. The first field indicates how much time
elapsed since the previous output. The second field indicates how many characters were output this time. This information can be used
to replay typescripts with realistic typing and output delays.
The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. Script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is utilized by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO csh(1) (for the history mechanism), scriptreplay(1).
HISTORY
The script command appeared in 3.0BSD.
BUGS
Script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
AVAILABILITY
The script command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
