Maybe instead of for use a while, like so:


cat mylist | while read line
do
echo "Next file is: $line"
done

Try this:


awk -va=0 -vb=0 '{if (NR!=1) {b=b+$NF-a}; if (NR==1) {print $0,b} else {print $0,b}; a=$NF;}' file.txt

Maybe try this (I don't think elsif works in awk):

awk '{for(i=1; i<NF; i++) {if(($i-$(i+1)) < -10) {printf "-2 "} else if(($i-$(i+1)) > -10 && ($i-$(i+1)) <0) {printf "-1 "} else if(($i-$(i+1))>0...

You could try a script like this (replace /path/to/file with the actual path to the file you are grepping for errors):


#!/bin/bash

no_errors=`grep -c "Error due to syntax" /path/to/file`
...

You might try this, however it will not echo the "Overwrite previously saved":

grep '#' /diff_dir/outfile | awk -F'#' '{print $NF}' | awk -F':' '{print $NF}'

I guess you can't have nested backticks (`) and probably this is why it's throwing those errors.

You could try $() instead of ``, as in:


X=`cal $(date +%m) $(date +%Y) | grep -v '[A-Za-z]' |...

This will work also (obviously not as short written as Franklin52's solution):


#!/bin/bash

#TARGET dir should end with /, as in /home/user/

TARGET="/your/dir/"...

Because I didn't know about the basename command? :D

But you're right, it's the best for this task, since this is what it's designed to do.

Thanks for the heads up.

Or with awk:


X="/TEMP_REGRESSION/regression/TESTSUITE/TestCases/Test1201/ext_libs/DATA/INTERNAL/pad_ext.lef"

echo $X | awk -F'/' '{print $NF}'

I'm beginning to get a bit confused about what you want... Do you want to have the same files on the mail server and the backup server (as in, get a list of all the files currently on the mail server...

If your system supports the -A option for grep, you could try something like this (I'm assuming that the records are stored in a file called file.txt, which does not contain the actual header...

coolatt, if I'm reading this right, you want to delete from the backup server, for each xyz,2* group, all but the most recent file pertaining to each group.

Or in a perhaps more familiar way, you could try something like this:
