2. #!/bin/bash
4. Redis_host=localhost
6. redis_port=6379
8. Redis_db=1
14. keyname=redis:hash:*
16. Keyfile=key.txt
18. echo "KEYS $KEYNAME" | Redis-cli-h $REDIS _host-p $REDIS _port-n $REDIS _db > $KEYFILE
24. Outfile=valuelist.txt
26. tempfile= $OUTFILE. tmp
28. echo > $TEMPFILE

32. Do
34. Echo $key
36. #echo "Hgetall $key" | Redis-cli-h $REDIS _host-p $REDIS _port-n $REDIS _db >> $TEMPFILE
38. echo "GET $key" | Redis-cli-h $REDIS _host-p $REDIS _port-n $REDIS _db >> $TEMPFILE
40. Done

2. Organize and export the results

[Plain]View Plain copy

1. Cat $TEMPFILE |xargs-n 2|awk-f "" "-V keyname= $KEYNAME ' {print ' hset ' KEYNAME '" $, "\" "$ $" \ "} ' > $OUTFILE

One of the Xargs-n 2 is a line of 2 lines, the line break with a space instead

Then use awk to separate the spaces, which is the value of Keynam.

Convert to Hset format again, which uses the KeyName variable, which is predefined with-V.

Finally, convert to Hset KEYNAME KEY "VALUE" format.

3. Result of import conversion
