如何正则表达式strace过程?
How to regex strace process?
我正在尝试使用此命令跟踪多线程进程:
sudo strace -p1523 -e write -f
但是输出了很多不必要的信息示例:
[pid 1166] write(6, "[=11=][=11=]4716S5c1]2631]3e1c2a4"..., 517) = 517
[pid 1166] write(6, "[=11=]F[=11=][=11=]BA3764296p631Zt6xhi315"..., 126) = 126
[pid 1166] write(6, "0D4603O5K61`105y551456611z5"..., 413) = 413
[pid 1166] write(6, "[=11=]D4603O5L7362$U?a40s4)\5N0", 31) = 31
[pid 1166] write(1, "None\n", 5) = 5
我如何才能仅跟踪此正则表达式 write\(1, "(.*)", [0-9]*\)
中的文本?
我试过:
sudo strace -p1157 -e trace=/write\( -f
#output ------------
strace: regcomp: write(: Unmatched ( or \(
#also
sudo strace -p1157 -e trace=/write\(1.*\).* -f
#output ------------
strace: invalid system call '/write(1.*).*'
strace 正则表达式在某些方面有所不同吗?
像这样:
sudo strace -f -p1523 -e write 2>&1 | grep -o 'write([^)]\+)'
或 bash:
sudo strace -f -p1523 -e write |& grep -o 'write([^)]\+)'
输出
write(6, "[=12=][=12=]4716S5c1]2631]3e1c2a4"..., 517)
write(6, "[=12=]F[=12=][=12=]BA3764296p631Zt6xhi315"..., 126)
write(6, "0D4603O5K61`105y551456611z5"..., 413)
write(6, "[=12=]D4603O5L7362$U?a40s4)
write(1, "None\n", 5)
