How about sed?


var='select_id="x_0' #you need not escape " when using single quote
sed "/$var/,/from/" x.txt

perl -lne 'BEGIN{@id=split(/,/,"SL,SN, TB, pad up, pad down, time up to down, time down to pressure switch, time down to ready, time down to sweep");}

-t "." this option stands for identifying delimiter and here its dot
-k3.1,3.4n "k start,stop" stands for field to start and stop at...first am sorting on years which happens to be 3rd column..so...

You can change the text highlighted in red to your customized occurrence...
I hope i got your requirement right..

For files
1>First check with the below command if you are satisfied with the results

ls * | perl -lne '{$Tget=$_;s/\./ -- ttgductoog ggdté gollogtd./;print "$Tget"." <--TO--> "."$_";}'


2>If...

if its only for the same date and same month then try using this..


ls www* | sort -t"-" -k5 -r

perl -alne '{if(/^\d/) {$val=$F[0];$F[3]=~s/.*?-(\w+):(\d)/$1 $2/;print "$F[0] $F[1] $F[3]";} else{ if(/^100/){$F[2]=~s/.*?-(\w+):(\d)/$1 $2/;print "$val $F[0] $F[2]";next;}}}'


I thought this...

I guess that limited to only bash...
History command inside bash script - Unix and Linux (http://unix.stackexchange.com/questions/5684/history-command-inside-bash-script)

sh is used to execute the piped output from sed command...you can use your "shell" name there

perl -alne '{if(/^\d/) {$val=$F[0];$F[3]=~s/.*?-(\w+):(\d)/$1 $2/;print "$F[0] $F[1] $F[3]";} else{
if(/^ +/){$F[2]=~s/.*?-(\w+):(\d)/$1 $2/;print "$val $F[0] $F[2]";next;}}}' input_file


Hope...

Hope this helps...

Right elixir...new to PERL workarounds for files..somehow forgot its usage:wall:
Below code would be more efficient...:b:

perl -lne '{$Tget=$_;$_=~s/(.*?)(\d+)$/$2 $1/g;rename "$Tget", "$_"}' temp

Ok.
1>First store all the necessary directory names into one file like "temp" and execute as usual to check if this is satisfying your conditions

No my script doesn't work for these directories you have mentioned since its different conditions all together....But you can use the logic in my script as a workaround ..let me know if any help...

1>Verify is these are the conditions you require by just printing the mv command

ls *ext | perl -F"--" -alne '{if($#F==1){
if($F[1]=~/(\d+).ext/){ $p=$1;$F[0]=~s/^/$p /g;$F[1]=~s/$p//;print "mv...
