Bash background (&) with control operators (&&)

I have a set of files to copy and decompress, and want to do these operations concurrently with a script.

Manually it would be something like:

Code:

cp /src/file1.gz /dest/ & && gzip -d /dest/file1.gz &

cp /src/file2.gz /dest/ & && gzip -d /dest/file2.gz &

cp /src/file3.gz /dest/ & && gzip -d /dest/file3.gz &

The single & is intended to background the processes, while the && is intended to execute the gzip process if and only if the cp completes successfully.

My script is:

Code:

#!/bin/bash

FILES="*file$(date +"%m%d")*.gz"

DIR_SRC="/src"

DIR_DEST="/dest"



if [ -d $DIR_SRC ]; then

    for f in $(ls $DIR_SRC/$FILES); do 

        logger -s "cp_incoming.sh: processing $f";

        cp $f $DIR_DEST & && gzip -d $DIR_DEST/$(basename $f) &; 

    done

else

    logger -s "cp_incoming.sh: $DIR_SRC was not found - exiting"

    exit 1

fi



exit 0

When I run it, bash gets angry with the following error:

Code:

$ ./cp_incoming.sh 

./cp_incoming.sh: line 9: syntax error near unexpected token `&&'

./cp_incoming.sh: line 9: `        cp $f $DIR_DEST & && gzip -d $DIR_DEST/$(basename $f) &; '

So what is the proper syntax to accomplish this?

TIA

Figured it out:

Code:

#!/bin/bash

FILES="*file$(date +"%m%d")*.gz"

DIR_SRC="/src"

DIR_DEST="/dest"



if [ -d $DIR_SRC ]; then

    for f in $(ls $DIR_SRC/$FILES); do 

        logger -s "cp_incoming.sh: processing $f"

        cp $f $DIR_DEST && gzip -d $DIR_DEST/$(basename $f) &

    done

else

    logger -s "cp_incoming.sh: $DIR_SRC was not found - exiting"

    exit 1

fi



exit 0

I just needed to treat the whole cp && gzip operation as one process to be backgrounded. Removing the semicolons at the end of the lines int he for loop also helped.
