我可以使用以下命令将所有行合并为一行
cat input.txt | tr -d '\n' > output.txt
但正如您在下面看到的,我的数据是用制表符和双逗号分隔的。
mail._domainkey IN TXT ( "v=DKIM1; k=rsa; t=s; s=email; "
"p=MBIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AEIIBCgKCAQEAxZfSF9WkStkz1A0tbSNWAEdyHiWfenEeihvzVn8mCOx7nsUBYnEDocbDb8P0pTHS8MVNZ4jhXSwkg5mc6+NVgyZIctSogUMdD1ddGsYDfUHgT/d5tsVTzecgRtTtpdxibRyh1HY5Zmg2wxFLuCPqMPVeJHjwfKwwQHHCQtIVH+b+QvmF6hxODu73UwNUaG1cr8UkLqoQexTGoS"

我怎样才能得到以下输出?
mail._domainkey IN TXT ( "v=DKIM1; k=rsa; t=s; s=email; p=MBIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AEIIBCgKCAQEAxZfSF9WkStkz1A0tbSNWAEdyHiWfenEeihvzVn8mCOx7nsUBYnEDocbDb8P0pTHS8MVNZ4jhXSwkg5mc6+NVgyZIctSogUMdD1ddGsYDfUHgT/d5tsVTzecgRtTtpdxibRyh1HY5Zmg2wxFLuCPqMPVeJHjwfKwwQHHCQtIVH+b+QvmF6hxODu73UwNUaG1cr8UkLqoQexTGoSqqmGCYGKk5ImzSIoa40L1gpcSPtIWbsVTSXK1FLsovGHd7NMmEHBgv2WabpDL4BQeEfSZC0Rk5sZEaWrepiHBiTcNjhb5tyLkgxmUIW21sOA+2kmChQUwyp10qDaP5h/+s7R0arQIDAQAB" ) ; ----- DKIM key mail for domain.com
答案1
cat input.txt | tr -d '\n\r\t\"' > output.txt
这应该可以正常工作。
答案2
我认为它们不是制表符而是空格。 Perl 的工作原理:
cat input.txt | perl -00 -pe 's/"\n\s+"//g' > output.txt
答案3
使用GNUsed
$ sed -z 's/"\n[^"]*"//g' input_file > output.txt
$ cat output.txt
mail._domainkey IN TXT ( "v=DKIM1; k=rsa; t=s; s=email; p=MBIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AEIIBCgKCAQEAxZfSF9WkStkz1A0tbSNWAEdyHiWfenEeihvzVn8mCOx7nsUBYnEDocbDb8P0pTHS8MVNZ4jhXSwkg5mc6+NVgyZIctSogUMdD1ddGsYDfUHgT/d5tsVTzecgRtTtpdxibRyh1HY5Zmg2wxFLuCPqMPVeJHjwfKwwQHHCQtIVH+b+QvmF6hxODu73UwNUaG1cr8UkLqoQexTGoSqqmGCYGKk5ImzSIoa40L1gpcSPtIWbsVTSXK1FLsovGHd7NMmEHBgv2WabpDL4BQeEfSZC0Rk5sZEaWrepiHBiTcNjhb5tyLkgxmUIW21sOA+2kmChQUwyp10qDaP5h/+s7R0arQIDAQAB" ) ; ----- DKIM key mail for domain.com
