Shell Programming and Scripting

Hi,

I have three files as below:

Code:

AA.DAT20110505063903.Z
AA.DAT20110405062903.Z
AA.DAT20110305061903.Z

All the above files are appended with Date and timestamp in compressed format.

I need to extract AA.DAT20110505063903.Z(which is the latest file) from one server and uncompress it to AA.DAT before FTP'ing to different server.

Please let me know how to perform this using Script.

Thanks in advance
Sue

Please use [code] and [/code] tags when posting code, data or logs etc. to preserve formatting and enhance readability, thanks.

Code:

A=$(ls -1 AA.DAT*.Z| sort -k 1.7,1.14n| tail -1); compress -d $A; mv ${A%.*} $(echo $A| cut -c1-6)

Hi,

When i executed this command, i am getting last file instead of first file. Please help me out.

Thanks
Sue

Hi,

I could get the desired file by changing the code to

Code:

ls -1 .AADAT*.Z| tail -1

But when i am trying to execute the entire command

Code:

A = (ls -1 AA.DAT*.Z| tail -1); uncompress -d $A; mv ${A%.*} $(echo $A| cut -c1-6) i am getting  syntax error: `(' unexpected

Please assist me how to keep this in a script.

Note: Since I am a novice to scripting, I am really facing tough time to get used it.

Thanks
Sue
