因为你标记了tcl

set fh [open "filename"]
set contents [split [read -nonewline $fh] \n]
close $fh
set filtered [lsearch -inline -not -regexp $contents {bit_top.*(FDIO|REDEIO)}]

导致

def {u_bit_top/connect_up/shift_reg[7]

lsearch documentation.
但实际上您只需要grep

grep -Ev 'bit_top.*(FDIO|REDEIO)' filename

你们一直很亲密！）

sed '/bit_top.*FDIO/d' input

只需向sed输入一个与所需内容相匹配的正则表达式...

使用sed

$ sed -E '/bit_top.*(REDE|FD)IO/d' input_file
def {u_bit_top/connect_up/shift_reg[7]

您可以按照以下方式使用GNU AWK完成此任务，让file.txt内容

abc {u_bit_top/connect_down/u_FDIO[6]/u_latch}
ghi {u_bit_top/seq_connect/p_REDEIO[9]/ff_latch
def {u_bit_top/connect_up/shift_reg[7]

那么

awk '/bit_top/&&(/FDIO/||/REDEIO/){next}{print}' file.txt

给出输出

def {u_bit_top/connect_up/shift_reg[7]

说明：如果行包含bit_top AND（FDIO OR REDEIO），则转到next行，即跳过它。如果未发生这种情况，则仅编辑print行。

• （在GNU Awk 5.0.1中测试）*

只需稍加修改，就可以在sed中实现复合模式（例如*bit_top*FDIO*）。
运算放大器电流sed的两个变化：

# daisy-chain the 2 requirements:

$ sed "/bit_top.*FDIO/d;/bit_top.*REDEIO/d" file
def {u_bit_top/connect_up/shift_reg[7]

# enable "-E"xtended regex support:

$ sed -E "/bit_top.*(FDIO|REDEIO)/d" file
def {u_bit_top/connect_up/shift_reg[7]
