我有一个包含重复模式的文件，如下所示：
set m [ meas new $proj rajesh ]
meas $m set_type lvf_timing
abcde erft 1213
234 456 897 00000000000000
once upon a time
set t [ table new $m pvbt_table ]
table $t set_region_set_name lvf_clusters
table $t set_instance_condition derate_instance_condition
table $t set_corner_condition derate_corner_condition
set a [ axis new $t parameter_axis CPS]
set a [ axis new $t parameter_axis RPB]
set a [ axis new $t parameter_axis periphery_Vt]
set a [ axis new $t process_axis]
set a [ axis new $t voltage_axis]
set a [ axis new $t temperature_axis]
set a [ axis new $t bias_axis vdda]
set t [ table new $m table ]
table $t set_equation {derate_equation pvbt_table}
table $t set_region_set_name lvf_clusters
table $t set_corner_condition derate_corner_condition
set a [ axis new $t parameter_axis CPS]
set a [ axis new $t parameter_axis RPB]
set a [ axis new $t parameter_axis periphery_Vt]
set a [ axis new $t process_axis]
set a [ axis new $t voltage_axis]
set a [ axis new $t temperature_axis]
set a [ axis new $t bias_axis vdda]
我希望处理该文件，以便所有此类模式都得到如下修改：
set m [ meas new $proj rajesh ]
meas $m set_type lvf_timing
abcde erft 1213
234 456 897 00000000000000
once upon a time
set t [ table new $m table ]
table $t set_region_set_name lvf_clusters
table $t set_corner_condition derate_corner_condition
set a [ axis new $t parameter_axis CPS]
set a [ axis new $t parameter_axis RPB]
set a [ axis new $t parameter_axis periphery_Vt]
set a [ axis new $t process_axis]
set a [ axis new $t voltage_axis]
set a [ axis new $t temperature_axis]
set a [ axis new $t bias_axis vdda]
答案1
你需要这样的东西：
sed '/table new.*pvbt_table/, /^$/d;/pvbt_table/d' input_file
