Have you tried comm?

This is posted in the Shell Programming and Scripting forum, but the way you are invoking your functions looks like you want to write a C function (except for using single quotes instead of double...

awk 'NR == FNR{a[$1] = $2; next}
{for(x in a)
{gsub(x, a[x])};
print}' S_CHAR.cfg TEST.out

awk 'NR == FNR{a[$1] = $2; next}
{for(x in a)
{gsub(x, a[x])}; gsub(/\\/, X);
print}' S_CHAR.cfg TEST.out

Try this then:

FOLDER="/nas/testfolder"
FILE=$(ls -alt ${FOLDER} | awk '$NF ~ /^Test/ {print $NF}' | head -1)
if [[ -z $FILE ]]
echo "No file name matches your pattern in $FOLDER"
else
...

find /home/user/log -type f -name "*.log" | xargs vdir --time-style="+%s" | awk -v d="$(date +%s)" '{printf "%s\t%d\n", $7, (d - $6)/60}'

You know what to change ;)

I think I have a fix for my code above. Try this:
FOLDER="/nas/testfolder"
FILE=$(ls -alt ${FOLDER} | awk '$NF ~ /^Test/ {print $NF}' | head -1)
FILE_TIME=$(date --reference=$FOLDER/$FILE +%s)...

Try this:

ls -al | awk '$NF ~ /pattern/ {print $7,$8,$9}' | sort -rM | head -1Long list of all files in the current directory showing hidden files. Pipe to awk. If the last field (the file names)...

find /user/home/log -type f -name "*.log" -mmin -$((X * 60))

you can replace 'X' with number of hours, "/user/home/log" with the directory and "*.log" with your required file format

I don't think OP want blank space to be escaped. I don't see blank space escaped in OP's expected output.

I guess OP want to escape only those characters defined in variable SPECIAL_CHARS

Try alsoawk -v X="& ;" -v E='\' '{gsub(/./,"&|",X); sub (/.$/,"", X); gsub (X, "\\" E "&")}1' <<< 'abcd fkaj&dsdsd'
abcd\ fkaj\&dsdsdIf you know the escape char is back slash, this may work:
awk -v...

Another approach:
SPECIAL_CHARS='& ;'
ESCAPE_CHAR='\'
echo 'abcd fkaj&dsdsd' | awk -v SC="$SPECIAL_CHARS" -v EC="$ESCAPE_CHAR" '
BEGIN {
n = split ( SC, A )
}
...

Awk :
$ echo "abcd fkaj&dsdsd" | awk 'gsub(/[[:punct:]]|[[:space:]]/,"\\\\&")'
abcd\ fkaj\&dsdsd

Python re module maybe handy for that task:
echo "abcd fkaj&dsdsd;"|python -c 'import re;import sys;print re.escape(sys.stdin.read().strip()),'

# echo "abcd fkaj&dsdsd" | ruby -e 's=gets; puts s.gsub(/([& ;])\1*/,"\\\\\\1")'
abcd\ fkaj\&dsdsd

Actually I am confused about post1's example , whether example output is expected output / error in output / escape char missing output ?

It will match any string that is at least 1 and at most 50 character combination of following characters:


dash
lowercase alfanumeric characters
uppercase alfanumeric characters

This should be closer - replace the echo statements with call to your processing function/script:

function period
{
date=${1:today}
period="$(date -d "$date" +"%d.%m.%u")"
[[ $period...

Can you paste the code here again? If there is any space after the assignment "=" then you might have a problem.

You may also try if this works. Instead of assigning date to a variable simply have...

The standards specify that options should come before operands; not after. There are ways to work around that, but I don't see any real reason to bend the guidelines for what you're trying to do. ...

Depending on your OS flavour and version (please tell us - it does really help) you may be able to issue:-
date --set="today + 1 day"

I hope that this helps, but if not, a good search of these...

With GNU date:
future=`date -d"+$x days"`
past=`date -d"-$x days"`

Also, take a look at this link...

I'd use the written out pathname of the users homedirectory instead of the ~ notation.

What is the content of your script:

. ~xcrukusr/.bash_profile_xcruk

?

It seems , $XCR_HOME and $XCR_CFG are not ( are unknown to cron which mean they are not defined )!!!

(sigh) Did you ever bother to search (https://www.unix.com/faq.php?faq=pt_faq#faq_pt_faq_how_post) these fora? You might have come across the solution...
