Hey...

Curious as to how to get the following to work remotely over SSH. The

cmd is used to remove redundant lines, while maintaining order in the

output file.

The following works if I insert it in the remote term.

  cat /dog/aaa.dat | awk '!a[$0]++' > /dog/aaa.dat_tmp

However I'm unable to get the cmd to work via SSH from the local to

the remote. I've tried the following...

ssh  crawl_user@67.205.11.111  cat /dog/aaa.dat | awk '!a[$0]++' >

/dog/aaa.dat_tmp

ssh  crawl_user@67.205.11.111 ' cat /dog/aaa.dat | awk '!a[$0]++' >

/dog/aaa.dat_tmp '

ssh  crawl_user@67.205.11.111 " cat /dog/aaa.dat | awk '!a[$0]++' >

/dog/aaa.dat_tmp "

ssh  crawl_user@67.205.11.111 ' cat /dog/aaa.dat | awk '\!a[$0]++' >

/dog/aaa.dat_tmp '

ssh  crawl_user@67.205.11.111 " cat /dog/aaa.dat | awk '\!a[$0]++' >

/dog/aaa.dat_tmp "

ssh  crawl_user@67.205.11.111 ' cat /dog/aaa.dat | awk '"\!"a[$0]++' >

/dog/aaa.dat_tmp '

ssh  crawl_user@67.205.11.111 " cat /dog/aaa.dat | awk '"\!"a[$0]++' >

/dog/aaa.dat_tmp "

In some cases, the cmd returns -- bash: !a[$0]++: event not found

In the case

ssh  crawl_user@67.205.11.111 " cat /dog/aaa.dat | awk '\!a[$0]++' >

/dog/aaa.dat_tmp "

  the return is:

    awk: \!a[bash]++

    awk: ^ backslash not last character on line

The escapsed cmds seem to work, but in reality, only generates the 1st

line in the file!

  ssh  crawl_user@67.205.11.111 " cat /dog/aaa.dat | awk '"\!"a[$0]++'

> /dog/aaa.dat_tmp "

Thoughts/comments???

Thanks
