Practice folder contains many files and im interested in extracting file which starts with abc* ghi* xyz* . I need to do variety of operations for different files. if file starts with xyz* then i need to move to some destination otherwise some other destination. I am not able to make wildcard search working in if loop. can someone help me to fix this.
Code:
#!/bin/sh
cd /home/practice
for file in abc* ghi* xyz*
do
if [$file = xyz*];
then
#echo $file;
thetime=`date +%d%M`;
name=${file%\.*}
#echo $name"_"$thetime"."xml
#mv ${file} /test/dest1/$name"_"$thetime"."xml
else
#mv ${file} /test/dest2/$name"_"$thetime
fi;
done
In Bourne shell /bin/sh you will need to extract the heading of the file to test against. The if will only accept a literal value to compare to. You might consider the following:-
Code:
#!/bin/sh
cd /home/practice
for file in abc* ghi* xyz*
do
testval="${file%${file##???}}"
if [ $file = "$testval" ];
then
:
:
It might look a bit scary, but what the extra line does is to slice up the string. You could do this with cut but that spawns another process, so it can cost a lot of time if this is in a loop for lots of files.
The % and # markers are then followed by descriptions of how to split the line. The second part ${file##???} cuts the first three characters. It seems odd, but given that is what you want, it is the fed back in to the first part which then excludes everything from the string apart from what was worked out in part 2.
So, for a file name of xyz12345678, part 2 evaluates to 12345678, so part 1 the removes this from the end of the whole file name and you are left with xyz You can then use this in your if statement.
I hope that this helps,

Thanks for your reply but its not working . I think i have not explained the question well or did not understand your explanation. example for file in
/home/practice catalog
code:
#!/bin/bash
mkdir A1 A2
for file in abc* ghi* xyz*
do
if [[ $file == abc* ]]; then
echo "Matched file is: $file";
mv $file "A1"
else
echo "Matching other than abc*"
mv $file "A2"
fi;
done
Two temp dirs are created by the script and after execution , i can see the abc*files in A1 and rest of thefiles in A2.

Hi Experts,
We are developing a script which will wait for the trigger file(with datetime in the trigger file name).
But the problem is when I use 'while' loop to wait for the file, it waits for the filename with wilcard in it that is wait for 'Trigger*.done' file. :eek:

I'm sure this is by design, but using something like
for f in dir/*
do echo $f
done
produces unexpected (to me) results if run against an empty directory. I'd have expected it to not execute the loop, but it actually calls it with f set to 'dir/*'.
Now I know that I'm trying to protect... (2 Replies)

Hi,
I need to search through a file to find the last one occurence of my data.
File1 is like this:
sososo
abc123

I need to loop through to identify the last occurence of "abc".
So "abc345" is the record that I need.
Can someone give me some ideas? (9 Replies)
