I suggest you read the man page of the shell which you didin't tell us any specifics about.

"export" is not an assignment, it just marks an already assigned vaiabl for export when a new shell...

sh, bash and ksh sets variables with just the "=" sign (i.e., aa=boo) while csh and tcsh sets variables with set at the beginning of the line (i.e., set aa = boo) ...

You were hit by a parser bug:

b\
c

b\

a
the next lines are not appended and missing in the output.
The bug is fixed in recent versions of tcsh.

BTW if you...

Just so. Some versions of csh have bugs related to it. The ad-hoc parser strikes again.

I have never worked with any csh variant, but, at least with some implementations, you can get trace data if you set the echo and verbose variables (set echo verbose). Seeing the commands before and...

If you login to a local terminal, you talk to /bin/login, if you login with sshd it goes its own way, but these days everything talks to the same login system -- pam. (pluggable authentication...

Any numerical operation to that field will make it numerical.

You can also do this by *1, /1 like :)
Just careful with the strings. String will become 0

I'm surprised this works for you. If nofields contains:

Replace if(i not in a ) with if ( ! ( i in a ) )

Using awk
awk '{$1=$1}1' file

You can set colsep to comma to generate a CSV output:
set colsep ,

sqlplus -s $AIM_PSWD << EOF > sql.out
set feed off
set head off
set pages 0
select * from <table>
where <condition>;
EOF

try that.

I don't think this is the best way for handling this task.

I would suggest using SQL Loader (http://docs.oracle.com/cd/B19306_01/server.102/b14215/ldr_concepts.htm) for loading your colon...

Disregard my previous post.

-r FileName tells if FileName is readable by the current process.

you can man test

So, you will see those if both files are readable (you have...

Using perl is one option:
perl -e 'use POSIX qw(strftime); print strftime "%y%m%d",localtime(time()- 3600*72);'
Or you can use Perderabo's datecalc script in the thread that I posted.

I really don't understand what you are trying to achieve!

But you can define the file names in a variable inside BEGIN block and do something like below to get your desired output:

@juzz4fun, if you are using a for loop, then there is no need to use ls command inside.

That useless of ls (http://partmaps.org/era/unix/award.html#ls) command. You can simply use the variable: i...

I'm not sure I understand your question. If you man you want to move file_123 to folder_123 and instead of just removing file_, try:
#!/bin/ksh
for i in file_*
do mv "$i" "folder${i#file}"...

The simple thing is to just use bash, ksh, or any other POSIX conforming shell (I used ksh for this example):
#!/bin/ksh
for i in file_*
do echo mv "$i" "${i#file_}"
done
if the commands...

You could print out the header directly and then just work on the rest:

$ head -1 infile; awk 'BEGIN{FS=OFS=":"} NR > 1 {$3+=1000; print}' infile| sort -t: -k3n

On Solaris use /usr/xpg4/bin/awk rather than awk

The script works by using the double quote as both input and output field separator.

If there are no fields with double quotes, then the...

echo "$no_x_code_list" is a list.
Not nice for awk. Convert to a file format and feed that to awk.
awk reads from stdin when the filename is '-'.
echo "$no_x_code_list" | tr ' ' '\n' | awk -F':'...

Here is an explanation:
awk -F':' '
# NR == Total number of records read from all input file.

Let us say if you have list of X codes in file: no_x_code_list

Assuming fields in your file: input_file.csv are separated by colon :, you could do something like:
